  1. How Magnomer Magnetic Ink is Used to Enhance Recycling Efforts

    How Magnomer Magnetic Ink is Used to Enhance Recycling Efforts
    It’s no secret that we’ve got a plastic problem in our oceans. Despite significant recycling efforts and infrastructure, more and more plastic bottles and microplastics keep ending up there. The reality is that less than 6% of plastic bottles are currently recycled back into bottles. What a waste of effort!  So, what’s causing this giant gap between effort and impact? Well, in part, the labels! Those wrap-around bottle labels you see on your water bottle or any other beverage in a plastic container aren’t recycling-friendly.  Continue reading →
  2. Fighting Microplastic Pollution in the Ocean with Magnets

    Fighting Microplastic Pollution in the Ocean with Magnets
    Humans produce roughly 300 million tons of plastic waste annually. At least 10 tons of that ends up in the oceans. People experience it, first-hand, every single day. 20-year-old Fionn Ferreira, for example, loved the coastline where he grew up in southwest Ireland, but he hated the plastic that littered the beach and the sea. To make matters worse, the issue goes beyond the plastic we can see with our own two eyes. Continue reading →
  3. Recent Magnet Technology in Roller Coasters

    Recent Magnet Technology in Roller Coasters
    When you’re riding a roller coaster, the last thing you’re thinking is, “What’s the science behind this contraption?” Your thoughts are more aligned with “Yahoo!” or “Weeeeee!” Roller coaster technology is fascinating, though, and it just so happens that it utilizes magnets.  These days, your favorite roller coasters use electrically induced magnetic fields and a launch system to propel coaster trains forward and slow them down. Two primary types of launch systems used are the linear synchronous motor (LSM) and linear induction motor (LIM). LSM is generally the more popular choice, but LIM is cheaper, although it uses more power.  Continue reading →
  4. Scientists Use Pottery and Flint to Detect Magnetic Fields

    Scientists Use Pottery and Flint to Detect Magnetic Fields
    There’s a lot to learn about Earth’s magnetic field — did you know that it’s dented or that unpredictable geometric jerks can occur? You might know that the strength and direction of Earth’s magnetic field have changed over time — it has flipped numerous times in the history of our planet! Scientists want to study the pattern of this change to help make predictions about how the planet’s magnetic field will behave in the future.  Instruments for measuring Earth’s magnetic field have only been around for a few hundred years, but scientists have figured out other ways to analyze Earth’s magnetic field. This includes a new study using artifacts recovered in Jordan from the Neolithic period or the New Stone Age. Read on to learn more about this discovery and how it’ll impact the future of magnetic field research.  Continue reading →

  6. Scientists Work to Create the World’s Thinnest Magnet

    Scientists Work to Create the World’s Thinnest Magnet
    For years, researchers have been trying to make thinner, smaller two-dimensional magnets. Doing so would allow us to store data at a much higher density. Now, in an exciting reveal, Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have discovered an ultrathin magnet that operates at room temperature. This development could lead to all sorts of advancements in computing and electronics, including high-density, next-generation memory devices and tools for quantum physics.  Continue reading →
  7. Addressing Rare Earth Metal Supply Shortages with Recycled Hard Drives

    Addressing Rare Earth Metal Supply Shortages with Recycled Hard Drives
    Recycling rare earth magnets is an ongoing conversation in the permanent magnet industry. Over the years, the Apex Magnets team has compiled information about rare earth metal recycling to share with our community, including the future of urban mining. We’ve also shared information about various hard drive recycling projects and studies, such as Critical Materials Institute’s hard drive recycling process and Oak Ridge National Laboratory’s research on making rare earth magnet recovery more economically feasible. Now, Google is working toward finding ways to recycle hard drives from its data centers worldwide. Continue reading →
  8. Fast and Furious 9: Far-fetched Concepts of Electromagnetism

    Fast and Furious 9: Far-fetched Concepts of Electromagnetism
    The latest installment of the Fast and Furious franchise — Fast and Furious 9 — takes its reputation for daring (unrealistic) action scenes and really kicks it up a notch. It’s no longer “just” jumping from skyscraper to skyscraper in a car or cars parachuting from planes, now it’s space launches and an electromagnet attached to a plane that can literally pick a plummeting car right out of a free fall. But, hey — that’s the fun of movies, right? Go big or go home. We’re here for it, but we need to clear a few things up.  Continue reading →
  9. Magnetic Nanopowder For 6G Technology

    Magnetic Nanopowder For 6G Technology
    While carriers are still in the process of rolling out 5G communication in certain areas an even faster network technology, known as 6G (sixth generation), is taking shape. It really is humanity’s way — progress, progress, progress. Progress is never without its challenges, and there are still hurdles between 5G and 6G. Historically, one of the materials used in its production — epsilon iron oxide — has been difficult to produce in large quantities, making industrial application a challenge.  But, as one might have predicted, scientists have come up with a potential answer, developing and publishing a method for producing the rare form of iron oxide (III) at an accelerated rate, and demonstrating its use for 6G wireless communication.

  10. Magnetic Fields Help Form Planets

    Magnetic Fields Help Form Planets
    Have you ever wondered how planets form? So have scientists! Until now, scientists haven’t been able to figure out a solid reasoning for the creation of our solar system. In a recent study, a computer simulation shows that magnetism may be the "missing ingredient" in the recipe to make a planet that scientists have been searching for.  Continue reading →
