Magnets in the News

  1. Magnetic Personality: Wilhelm Weber

    Magnetic Personality: Wilhelm Weber
    Do you know how to measure magnetic flux? The unit of measurement to describe magnetic flux is a “weber.” You may not have known, but this unit is a tribute to Wilhelm Weber, a truly magnetic personality from the early 1800s who had a hand in some of the most significant breakthroughs within magnetism and electricity.  Continue reading →
  2. Magnetic Personalities: Heinrich Hertz

    Magnetic Personalities: Heinrich Hertz
    Anyone who’s taken a science class has heard of “Hertz.” To refresh your memory, Hertz is the unit of frequency, with a cycle per second equally 1 hertz. The man behind the name is Heinrich Rudolf Hertz — a German physicist who discovered radio waves that had a tremendous impact on the world in the 20th century.  Continue reading →
  3. 2020 Magnet News Round-Up

    2020 Magnet News Round-Up
    From using magnets to help social distancing to breakthroughs in magnetic field research— 2020 was an eventful year in the world of magnetic discoveries. In order to celebrate the end of the year, let’s take a look back at some of our favorite magnetic news stories! Continue reading →
  4. Making Digital Technology Faster and More Efficient

    Making Digital Technology Faster and More Efficient
    There’s technology around us that wouldn’t be possible without magnets and their forces. One of the most common examples — memory.  Thanks to magnetism, and the spinning of electrons in one direction or the other, most of the information in the world can be encoded in hard disks or stored in memory drives.

  5. Jellyfish Galaxies and Their Magnetic Fields

    Jellyfish Galaxies and Their Magnetic Fields
    While we know that the magnetic fields in galaxies can contribute to star formation, one type of galaxy has left scientists questioning this fact. So called “jellyfish galaxies' ' fall into the center of a galaxy cluster, which get their name from their jellyfish-like tails. It’s been theorized that the rarified gas of jellyfish tails can also form stars, but research hasn’t been able to confirm this as these galaxies are difficult to study due to their low brightness. That is until now.  Continue reading →
  6. How Magnets Could be Affecting Your Watch

    How Magnets Could be Affecting Your Watch
    With technology all around us, almost everything has a magnet in it nowadays. It’s more than things you’d find at home like fridge magnets, computer speakers, and even your jewelry, though. At the hospital, you’ll find MRI machines filled with magnets and at the airport, there are security scanners and metal detectors. The magnetic fields surrounding our daily lives is stronger than ever before. You may wonder then, how do these magnetic fields interact with each other? Specifically, we’re going to look into if/how magnetization around us can pose a threat to something a lot of people can’t leave home without — a watch.  Continue reading →
  7. Megatesla Magnetic Field

    Megatesla Magnetic Field
    Most magnetic fields on Earth, even man-made ones, are actually not that strong. For years, experts have been researching strong magnetic fields created in laboratories. However, the magnetic strength of this research has been weak (relatively speaking). For instance — the geomagnetic field that affects compass needles is between 0.3 and 0.5 gauss while MRI technology used in hospitals generally produces fields of around 1 tesla, or 10,000 gauss.  No one has been able to successfully go higher than 1,200 tesla or slightly over 1 kilotesla.  That is, until now-- Continue reading →
  8. A New Magnetoelectric Effect is Showcased in a Crystal

    A New Magnetoelectric Effect is Showcased in a Crystal
    We talk about magnetism and electricity a lot as the two are linked together in many ways — from power lines generating a magnetic field to how magnets are used to generate electricity  (refresh your memory here). Even though it’s a common occurrence for these two to be linked, it’s not uncomplicated as electrical and magnetic properties of certain materials are also coupled with each other. Meaning, the electrical properties can be influenced by a magnetic field and vice versa.  Continue reading →
  9. New Magnetic Imaging Findings

    New Magnetic Imaging Findings
    Magnetic information-storage devices, such as floppy disks, credit card stripes, and hard-disk drives, have been getting smaller as the years go on. This size-reduction has been necessary as it allowed for more bits of data to be integrated into smaller devices. As technologists keep pushing the boundaries of just how much they can increase the storage density of these devices while keeping the devices themselves smaller and smaller, the limitations of this practice are being discovered.  Continue reading →
  10. MagSafe is Being Revived in Apple’s iPhone 12

    MagSafe is Being Revived in Apple’s iPhone 12
    With Apple’s newest iPhone launch, most people are talking about the 5G capabilities and camera quality. What stuck out to us though is their use of magnets!  Now, this isn’t new — we’ve written about Apple’s use of magnets over the years, which you can check out in this blog post here. We also know Apple has harnessed the power of magnets before when it comes to revolutionizing electronics — in 2018, Apple’s iPad Pro had a whopping 102 magnets in it! We got nerdy about that one in this blog post. What’s interesting about this MagSafe technology is that it’s not entirely new — Apple had used it in their Macbooks until 2016. So, why switch back and in the iPhone rather than Macbooks?  Continue reading →
