  1. 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 →

  3. Explaining Magnet Usage in the Netflix Original Stranger Things

    Explaining Magnet Usage in the Netflix Original Stranger Things
    Spoilers ahead if you haven’t finished watching Season 3 of Stranger Things! When a television show makes science references, they can either go over our heads or have us thinking “is that really true?”    We wrote a previous article about magnetic properties being discussed in the show: when the characters noticed things were going wrong, something “strange” was happening with their compass -- the needle was no longer pointing true North (though, it should be pointed to magnetic North). In this particular episode, they did an experiment and found that all of the compasses were deviating from pointing north, showing a very strong magnetic interference going on. We decided, for the most part, this event could be “real.”  Continue reading →
  4. Magnets Shown to Create More Power than Electrical Generators

    Magnets Shown to Create More Power than Electrical Generators
    By combining permanent magnets and field winding into a wound rotor system, researchers at Purdue University have come up with a way to reduce the size of some moderate-to-low electric generators while also increasing the efficiency.  Continue reading →
  5. How Magnets are Changing Mountain Bike Chainrings

    How Magnets are Changing Mountain Bike Chainrings
    There seems to be an increased trend of companies incorporating magnets into bike and bike accessory designs --the latest trend includes magnetic platform pedals. The goals of these innovations are to not only improve rider safety but to also improve their performance. One issue that many mountain bikers face is chain drop, although it’s not as common as it used to be since the invention of narrow-wide chainrings. MagSuck, a company based in Zhejiang, China, came up with an attractive solution for chain drop—magnetic bike chainringsContinue reading →
  6. 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 →
  7. Scientists Just Accidentally Created a Permanent Magnetic Liquid

    Scientists Just Accidentally Created a Permanent Magnetic Liquid
    For the first time, scientists have created a permanently magnetic liquid. While soft magnets —also known as a ferromagnetic liquid—exist already, this discovery is different. A soft magnet can exist in liquid form when it’s close to magnetic objects, but it only remains magnetized when in the presence of such an object. This magnetic liquid, however, remained magnetized even after...

  9. The University of Iowa Wins a Record Grant to Study Magnetic Fields

    The University of Iowa Wins a Record Grant to Study Magnetic Fields
    There have been exciting things happening in magnetism. NASA recently awarded the University of Iowa (UI) a significant grant—$115 million—to study the interactions between the Earth and Sun’s magnetic fields. The TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) project, the largest research project in the university’s history, will be part of NASA’s Explorers Program.  Why Study the Magnetic Fields...
  10. How Magnets are Used in Electronics

    How Magnets are Used in Electronics
    The cellphone in your pocket, the tablet on your bedside table, the radio in your office, and the computer you’re currently reading this post on—what do all three of these have in common? We use these devices and many others on a daily basis, but rarely do we think about what they’re made of and how they work. If it...
