Using magnets to treat heartburn

Traditionally, sufferers from heartburn had two options: Medication or the complete avoidance of any foods that might trigger acid reflux. Now, there is a third option, and it works using magnets.

Doctors have developed the LINX Reflux Management System to treat those with chronic acid reflux, which is a condition that occurs when stomach acid leaks up into the esophagus. This system is a bracelet of interlinked titanium beads that have cores of permanent magnets. In a minimally invasive surgery, this ring of magnets is placed around the esophagus just above the stomach.

When the patient swallows, the esophagus expands to allow food into the stomach, breaking the magnetic connection. However, the magnets are strong enough to prevent stomach acid from leaking up into the esophagus, thereby preventing heartburn.

So far, seven patients have undergone the procedure. One of them was 75-year-old Maxie Inman, who has been dealing with chronic heartburn since he was a teenager, according to The Post and Courier.

And how does he feel since the surgery?

“I’m in hog heaven as far as food is concerned,” he told The Post and Courier. “I can eat anything I want.”

Inman said that the recovery involved chest pain, constant hunger and nausea, but all of the symptoms have since passed.

All seven procedures have been performed by Dr. David Adams of the Medical University of South Carolina, who believes that the LINX will be a great option for many chronic sufferers of heartburn, though it is not appropriate for everyone. For example, Adams notes, those with a weak or precancerous esophagus or the morbidly obese would not be candidates for the surgery. Adams told The Post and Courier that of approximately 19 million Americans who suffer from heartburn, only about 500,000 would be eligible candidates for LINX.

Electric car powered by permanent magnets tops 2014 fuel economy list

An electric car that features permanent magnets in its motor was recently named by the U.S. Environmental Protection Agency and the Department of Energy as the most fuel-efficient vehicle for 2014 model cars, Auto Week reported.

In the EPA and DOE’s Model Year 2014 Fuel Economy Guide, the 2014 Chevrolet Spark topped the list by being able to travel 119 miles on the equivalent of a single gallon of gasoline, according to Environmental News Service. This figure is calculated after the car averaged 128 mpg equivalent in the category of city driving and 109 mpg when driving on the highway. EPA officials have said reading the guide’s efficiency estimates for cars and trucks is an effective way for consumers to compare fuel economy for vehicles.

“For American families, the financial and environmental bottom lines are high priorities when shopping for a new vehicle,” said EPA Administrator Gina McCarthy. “This year’s guide is not just about how the latest models stack up against each other. It’s about providing people the best information possible to make smart decisions affecting their pocketbooks and the planet.” Continue reading

Magnetic Experiment and Lesson Ideas

Magnetism is all around us. It is one of the greatest scientific and natural phenomenons in the world and an important part of science and other learning curriculum. However, it can get a bit complex, so how do we teach students about magnetism without confusing or boring them? Here are a few suggestions and lessons to try to engage and introduce students to the magical world of magnets.

First, start with the basics and give a simple demonstration of how magnets work. Before diving into a full experiment, it is important to teach students about some of the main principles of magnets such as: north and south poles; attraction and repulsion; and magnet strength. Once they have a reasonable grasp on the principles, a good science experiment to start with is an:

Iron filings experiment: Interactively show how and what metals magnets attract while also teaching students about Earth’s magnetic field. For this experiment, all you need is some neodymium magnets and iron filings. Feel free to check out our article for more guidance.

Now, that you’ve covered the basics, you can move on to more complex and practical magnet lessons like:

Magnets and Electricity
You can “get two for one” with this neat lesson idea on magnetism and electricity. The relationship between these two forces goes back many years. In fact, magnetic induction is measured in units called Tesla, for the famous scientist and pioneer of electricity, Nikola Tesla. The first simple motor design used a magnet, so teach students how to make a homopolar motor with this experiment.

Magnetic Levitation
Now that students know a little bit more about magnets and their functional capabilities, this project is a creative way to teach how they are applied in the real-world. For instance, the fast-moving Maglev train operates on magnetic levitation technology. Using a superconductor, liquid nitrogen and magnets, you can demonstrate how magnetism is used in real-world energy applications with this experiment.

How Temperature Affects Magnets
When using magnets in real-world applications, scientists and engineers must account for certain conditions. One of those conditions is temperature, because depending on what degree it is, it can affect magnetism. You can use this as a lesson idea as well and compare how cold and hot temperatures affect magnets.

Vehicle magnets act as moving marketing tool

As competition for customers grows more fierce, companies need to find new ways to attract their target audience. One marketing tool gaining in popularity is the vehicle magnet. To increase brand visibility even while workers are on the road, businesses could invest in vehicle magnets that stick to the side of cars, trucks or buses. Acting as a traveling billboard, these magnets can draw attention to the smallest of businesses to strengthen their brand image and reate more customers.

The advantage of a magnetic sign is being able to simply place the magnet over the surface of a car door rather than sending vehicles in the shop to get signs and slogans painted onto the vehicles directly. The fast installation of a vehicle magnet means no downtime for businesses, which is especially important for companies that are just starting or need their vehicle to deliver goods or other activities. If businesses choose to update their logo or contact information, they can simply obtain a new vehicle magnet and remove the old one with ease.

Businesses could imprint their name, slogans, contact numbers and small description of their services or products all on the same vehicle magnet. Made with permanent magnets, vehicle magnets are strong enough to stick onto the surface of vehicles securely.

Vehicle magnet manufacturers like Grand Image Inc. are seeing growing demand for these types of magnets to market their clients’ goods and services.

“We never realized how many of our clients were in need of this type of product,” said Margaret Vosburgh, marketing and communications associate for Grand Image Inc. “Our mission has always been to make our clients look good to their customers. Being able to offer such a great solution to their needs encourages us to keep looking for additional services and items to support their growth.”

How to make magnetic bumper stickers
In addition to having the option to buy vehicle magnets, companies could also choose to make their own. To craft a small bumper sticker, gather the following materials, according to It’s a Dome Life: printer, magnetic sheets, scissors and acrylic spray sealer as well as gloves and a mask.

Upload a picture to a photo edting application on a computer for the bumper sticker. Resize the picture to be the width and height of the bumper sticker. Add text to the photo and save it before printing. Insert the magnetic paper sheets into the printer and print the bumper sticker. Cut off the excess with the scissors.

To seal the bumper sticker and make it more durable against weather, use acrylic coating. It’s a Dome Life advises performing this step in an area with adequate ventilation to reduce chemical exposure and wear a mask and gloves while handling the acrylic coating. Then brush or spray the coating onto the image.

The last step is to place the finished bumper sticker on the back of the car. It’s a Dome Life said one bumper sticker lasted through an entire 180 mile road trip.

New giant magnets delivered for fusion reaction, molecular research

 

Magnets dedicated for research purposes are often some of the biggest magnets in the world, making their size a challenge in transporting them to their final destination. Recently, the International Thermonuclear Experimental Reactor (ITER) is preparing its facility in France to use a magnet for a fusion reactor, which involves a super-heated fusion reaction, Geek.com reported. The magnet in question is incredibly powerful, measuring 13.5 Tesla (T) – higher than some magnets at research institutions and magnetic resonance imaging machines that range between 3 T and 8 T.

Operating a fusion reactor could generate a larger amount of energy output than it absorbs. Recently, the facility obtained a 30,000 pound coil of magnetic cable, which is expected to surround a tokamak, which is used to contain plasma.

Damage to the coil itself may result in billions of dollars lost, which shows how tricky it is to move expensive pieces of equipment. Another operation involvingtransporting a giant electromagnet from Brookhaven National Laboratory to Fermilab was done at the risk of millions of damage, Phys.org reported.

“We cut trees down because we didn’t want to damage the device,” said Tim Green, Natural Resources manager for the Lab’s Environmental Protection Division. “If you hit it up against a tree, you’re going to damage and ruin a $25 million piece of equipment.”

Magnet to be used to study petroleum molecules
Another mega magnet measuring 21 T was delivered and installed at the National High Magnetic Field Laboratory (NHMFL) by Bruker Corporation, a manufacturer of scientific instruments for molecular and materials research. The magnet is considered the first 21 T magnet for Fourier Transform Ion Cyclotron Resonance (FT-ICR) in the globe. Described as the highest resolution mass spectrometry technique to currently exist, FT-ICR is used for various scientific applications, including petroleomics, or the study of the organic composition of petroleum.

Professor Alan Marshall, professor of chemistry and biochemistry at Florida State University and director of the high field FT-ICR program at the NHMFL, said the 21 T Bruker magnet is at full field and the 21 T FT-ICR mass spectrometer’s subsystems may be available in fall of this year.

“The 21 T FT-ICR magnet is based on the wealth of experience gathered in ultra-high field magnet technology for [nuclear magnetic resonance] and for MRI magnets,” said Gerhard Roth, ultra-high field magnet manager for Bruker. “Bruker is extremely pleased to supply this cutting-edge 21 T magnet to enable new scientific research directions in ultra-high field FT-ICR mass spectrometry.”

Permanent magnet market to surge to $22.9 billion by 2018

Many inventors and manufacturers buy magnets to help build their next ground-breaking technological innovation, and it shows with a new report by BCC Research. The market for permanent magnets is expected to have reached $15.1 billion in 2013 and surge to $22.9 billion by 2018. More demand for industrial magnets is anticipated to help contribute to the compound annual growth rate of 8.7 percent between 2013 and 2018. The permanent magnet market accounts for four magnet types: neodymium, samarium–cobalt, alnico and ferrite/ceramic. Firms around the world are in need of these types of magnets to produce green technologies and other devices.

“Robust growth has been seen in the demand for permanent magnets during the last decade, and it is expected to grow at a considerable rate due to increasing industrial applications such as electric power steering and engines, wind turbines and consumer electronics,” the BBC Research report said.

One type of magnet expected to generate almost all demand
Much of this growth will come from the United States and the Asia-Pacific region as global manufacturers continue to find ways to increase the efficiency of magnet-powered devices. Recently, numerous patents have been issued for inventions that feature permanent magnet motors, including those used in a washing machine made by major U.S. appliance manufacturer Whirlpool Corporation.

Another common household item that may be transformed by magnets includes toothbrushes. Inventors for Mitsumi Electric Co., Ltd. in Tokyo filed a patent for an electric toothbrush that contains a motor that generates a quick vibration motion back-and-forth. The toothbrush vibrates with the help of both a permanent magnet and an electromagnet, creating a rolling and brushing movement. According to the background information released by the Mitsumi Electric inventors, the electric toothbrush is made more efficient with the device’s motion converting mechanism, allowing for faster vibration yet little power loss.

Out of four magnet types, BBC Research predicted the neodymium magnet will continue to dominate in the permanent magnet market as the most in demand magnet. The study said neodymium magnets make up about 98 percent of all permanent magnet demand in the world. Sales of neodymium magnets will grow at an average of 10 percent each year through 2017.

“In terms of the volume of magnets produced, ferrite magnets constitute roughly 90 percent of global production, with [neodymium] magnets constituting 7 percent to 8 percent,” the BBC Research report said.

3 of the most powerful magnets in the world

The applications for magnets are too many to count. From doctors using the magnets found in magnetic resonance imaging equipment to scan bodies to homeowners buying powerful magnets for projects around the house. But just how powerful are magnets? One measure of strength is the Tesla, which is the equivalent of 10,000 gauss, according to How Stuff Works. While magnets typically used for MRI machines are measured between 0.5 Tesla to 3 Tesla, there are much stronger magnets housed in research institutions.

Here are three of the world’s most powerful magnets:

U of M’s monster MRI magnet
The University of Minnesota boasts having the most powerful magnet for MRI machines in the world, the Star Tribune reported. The magnet weighs 110 tons and was delivered to the university after being made by Agilent Technologies in England and making its journey across the Atlantic Ocean to its new home. The magnet will be utilized for the university’s Center for Magnetic Resonance Research and is expected to generate 10.5 Tesla, which should allow researchers to produce more detailed images of the brain.

“The kind of information that we need to generate an accurate wiring diagram of the human brain simply doesn’t exist,” said Kamil Ugurbil, director of the U of M’s MRI research efforts. “This will enable us to be unique in terms of human brain studies.”

Scientists at the university aim to develop the Human Connectome Project, which involves mapping the brain, with the magnet.

Energy Department’s magnet for physics experiments
While it’s not as big as U of M’s magnet, a 15-ton magnet still posed a massive challenge when it was shipped 3,200 miles from Long Island to the U.S. Department of Energy’s Fermi National Accelerator Laboratory’s in Batavia, Ill., a suburb of Chicago, The Christian Science Monitor reported.

James Siegrist, associate director of science for high-energy physics with the U.S. Department of Energy, called the Muon g-2 experiment – which the magnet will be used for – a significant part of the future of particle physics in the U.S.

The entire trip from Brookhaven National Laboratory, where the magnet was built, to the Chicago area is projected to have cost $3 million, which pales in comparison to the amount it would have taken to construct an entirely new electromagnet.

“It costs about 10 times less to move the magnet from Brookhaven to Illinois than it would to build a new one,” said Lee Roberts of Boston University, spokesperson for the Muon g-2 experiment, in a press release. “So that’s what we’re going to do. It’s an enormous effort from all sides, but it will be worth it.”

At the new lab, scientists from 26 institutions around the world will study the magnet as part of the Muon g-2 project. The research will entail observing muons, which are subatomic particles that are only present for 2.2 millionths of a second.

MagLab’s multi-shot magnet
The National High Magnetic Field Laboratory’s (MagLab) Pulsed Field Facility magnet located in Los Alamos National Laboratory in New Mexico has the potential to reach up to a staggering 100 Tesla. The multi-shot magnet, named for its ability to be used repeatedly, is capable of generating the highest nondestructive field in the globe. The 100 Tesla magnet is important in the scientific community because scientists can study how high magnetic fields affect the quantum behavior of phase transitions in solids, according to the MagLab’s site. Researchers may be able to improve knowledge about superconductivity and other scientific concepts through experiments that reveal the maximum strength of the magnet.

Surge in demand for tablets increasing rare earth consumption

With consumers increasingly looking to buy portable devices like tablets, consumption of rare earths may grow. According to Wall Street Daily, rare earth metals like neodymium will be in high demandthanks to drops in prices and higher purchases of tablet computers. Technology firms may want to buy magnets to incorporate into their tablet products and meet the growing demand.

The market for rare earth metals is expected to grow at an average rate of 9 percent each year between 2013 and 2018, according to business intelligence firm MarketsandMarkets. Demand for rare earths is projected to reach 192,000 metric tons by 2018.

Rare earth exports rose with this surge in demand with an increase of 34 percent in May compared to the previous month, according to data from the General Administration of Customs. In addition to data showing an upward trend in rare earth exports, shipments of this material gained 22.8 percent year over year.

Growth in tablet market 
The International Data Corporation recently revised its original forecast for this year’s global tablet market down to 245.4 million units from its previous forecast of 260.9 million units.

Tom Mainelli, program vice president of devices & displays at IDC, said there are two primary reasons for the tablet market slowing down. The first reason is that consumers are not upgrading to new tablets as fast as predicted and when they do, they are handing down old tablets to family members. The second is consumers may be eyeing phablets, defined as smartphones with screens that are 5.5 inches or bigger, instead of traditional tablets.

While recent reports have indicated tablet sales are slowing, a report by research firm Gartner found of all the consumer electronic devices in the market, tablets grew the most, ZDNet reported. Global shipments of tablets reached 270.7 million units this year compared to 195.4 million units last year.

Although sales may be less than anticipated this year, analysts predict the market will recover as tech manufacturers introduce bigger screens, according to IDC.

“The shift back toward larger screens will mark a welcome sea change for most vendors as the average selling price for these devices will remain roughly 50 percent higher than the average sub-8-inch device,” said Jitesh Ubrani, research analyst for IDC’s Worldwide Quarterly Tablet Tracker. “Microsoft is also expected to benefit from this shift as the share for Windows-based devices is expected to double between now and 2018.”

Permanent magnet motors crucial to reduce HVAC energy consumption

With eWith energy-efficiency regulations helping to reduce energy waste nationwide, manufacturers are most likely to looking to optimize their technology for well-known energy hogs like HVAC systems. HVAC, or heating, ventilation and air conditioning, consumes a huge amount of energy to properly regulate the temperature within buildings. An estimated 40 percent of the energy consumed by commercial buildings is due to HVAC use, according to Navigant Research. As companies looking to save on their heating and cooling bills while decreasing their energy use in compliance with energy regulations, firms may be investing in developing more efficient HVAC technologies. Initiatives like the federal Energy Star program headed by the U.S. Environmental Protection Agency are helping to boost consumer awareness about these technologies. Companies are responding to changes in demand for sustainable products by creating new technologies with better motors to make more efficient HVAC systems. The worth of the global market for energy-efficient HVAC systems will reach $33.2 billion by 2020, according to Navigant Research. Since motors are found in various devices and machines, having more optimized motors made from permanent magnets could greatly reduce energy use. Demand for energy-efficient motors growing Permanent magnets are often used in green technologies like wind turbines, and motors made from these materials are praised for their efficiency. Permanent magnet rotors, which are called EC motors in the HVAC sector, are known for greater motor control, according to Dan Foss, which makes energy-efficient solutions and services like electric motors. They work using the brushless DC motor (BLDC) principle, which allow them to have low air throughput. EC motors are similar to permanently excited synchronous motors (PNSMs), or permanent magnet motors. “A key factor for energy savings in building services is the use of variable speed drives for compressors, pumps and fans,” Dan Foss said in a report. “There are two decisive factors here: high efficiency of the machine and the motor and energy-efficient application control.” Demand for energy-efficient HVAC systems are expected to emerge in North America as well as Asia Pacific, which is projected to account for most of the growth for efficient HVAC systems for commercial buildings, according to Navigant Research. “Efficient forced air systems overwhelmingly dominate the North American market, but are much less common in Europe and Asia Pacific,” the Navigant Research report said. “Western Europe, where strong regulatory drivers strongly support energy efficient HVAC deployment, has made significant progress with respect to efficient ductless systems and efficient ventilation systems.”nergy-efficiency regulations helping to reduce energy waste nationwide, manufacturers are most likely to looking to optimize their technology for well-known energy hogs like HVAC systems.

Magnote device aims to change face of notebooks with magnets

A new project on the crowd-funding site Kickstarter is hoping to fund the world’sfirst paper notebook made of magnets, tech publication CNET reported. Regular paper pads got a magnetic reboot with the notebook known as the Magnote, which is made by design and development team orangemonkie.

Different from typical notebooks, the Magnote contains magnets that increase its functionality. The company said its notebooks are constructed usingneodymium magnets, which are considered to be one of the most powerful types of magnets in the world.

The company said it has made many prototypes of the Magnote, but hopes to expand production with the money raised from the Kickstarter campaign. The company aims to raise $35,000 before the clock runs out on the campaign on July 9.

“We want to make simple but useful notebooks which can contain our experiences and lives at every moment – something that can precisely capture our thoughts depending on our needs,” the Magnote makers said on their Kickstarter page. “That’s why we created Magnote, which is the world’s first notebook composed of magnets. It is the simplest way to both bind and separate all the books you need.”

How magnets change notebook design
The neodymium magnets make the books more portable and allow users to combine notebooks together by simply placing them together and aligning the binding.  The powerful magnets are located in the spines of the notebooks. If they do not need certain books, users can take them apart so they do not have to carry all of them. The uniformity and size of the notebooks also make it easy to stack and organize the pads.

The notebooks are expected to be available in different paper formats, from planners to grid paper to ruled pages.
