  1. Four Uses of Magnets and Magnetism in Movies

    Four Uses of Magnets and Magnetism in Movies
    Whether you’re a dedicated film buff or a casual movie-watcher, you’ve likely experienced the tropes of magnetism in film. In fact, magnetism has been a recurring concept shown in pop culture, from superheroes and supervillains to Netflix originals. While some uses are a stretch or don’t quite add up in real life, it’s still fun to see the different ways that filmmakers have incorporated the thing we’re most passionate about! Here, you’ll find our roundup of four ways magnets and magnetism were used in movies.  Continue reading →
  2. Here’s What Happens When You Heat Paramagnets

    Here’s What Happens When You Heat Paramagnets
    Magnets are a crucial part of collecting energy from heat. When one side of a magnet is heated, the other, cooler side will become more magnetic, which produces spin --flux of magnetism -- and creates electricity. Once paramagnets are heated up, though, nothing happens. That is until an international team of researchers and scientists found a way to capture heat and transform it into electricity using paramagnets, something that wasn’t thought to be possible.  Continue reading →
  3. Sea Turtles Find Their Birthplace with Magnetic Fields

    Sea Turtles Find Their Birthplace with Magnetic Fields
    Previous studies have shown that sea turtles use Earth’s magnetic field to help guide them at sea, similar to how sailors use latitude and longitude. Loggerhead turtles, in particular, have been known to swim thousands of miles to lay their eggs on Florida’s Gulf, as well as Atlantic coasts. What’s interesting is that recent research has found that these nesting places are actually within about 40-50 miles of where the turtles were born decades earlier.  Continue reading →
  4. Laser Light Turns Metals into Magnets

    Laser Light Turns Metals into Magnets
    Normally, it’s possible for light to transform the properties of a material; however, these properties must exist to be manipulated. Physicists now believe they have found a way to use lasers to transform the properties of a material, creating new properties. Specifically, they have discovered a way to make non-magnetic materials magnetic.  Continue reading →
  5. Magnets and Quality Control in the Food & Beverage Industry

    Magnets and Quality Control in the Food & Beverage Industry
    Do you know about the important role magnets play in the food and beverage industry? This is especially crucial during processing when metal contaminants can interrupt production, damage equipment, or lead to product recalls and consumer injury. Magnets are used to attract unwanted metal fragments (some as small as dust), whereas other methods of quality control (QC) — metal detectors and X-ray machines — are limited by how much they can accurately detect.

  6. The Use of Permanent Magnets in Electric Motors

    The Use of Permanent Magnets in Electric Motors
    Motors are all around us! They are practically indispensable in almost every major industry and can be found wherever there is mechanical movement. In the average household, you will likely find electric motors in your washing machine, microwave, refrigerator, ceiling fans, hairdryers, electric razors, and the list goes on. On an even smaller scale, micro-motors can be found in your most-used electronics — computers, laptops, and cellphones.   Continue reading →
  7. Removing Microplastics Using Magnets

    Removing Microplastics Using Magnets
    Using magnets to clean up the ocean isn’t new -—- we’ve even talked about magnets being used in cleaning up oil spills in the oceans before. The future of microplastic disposal in wastewater treatment facilities may be getting cleaned up thanks to one teenager’s science fair project. Irish student Fionn Ferreira recently won Google’s 2019 science fair with his inventive means to extract microplastics from water. Continue reading →
  8. The Magnetism Behind Stationary Exercise Bikes

    The Magnetism Behind Stationary Exercise Bikes
    Whether you’re an avid cyclist or new to the game, you’re likely familiar with a few popular stationary exercise bikes: Peloton, Schwinn, Echelon Fit, and NordicTrack, which all use magnetic resistance. There are four other types of exercise bikes: brake-based systems, direct contact, and fan-based systems, but magnetic resistance bikes are leading the stationary exercise bike, however. So, what makes magnetic resistance the most popular? Read on to learn more. Continue reading →
