  1. Scientists Could Now Control Magnetism Thanks to Metamaterials

    Scientists Could Now Control Magnetism Thanks to Metamaterials
    Scientists have long been trying to control magnetism — something that would do wonders for advancements in technology. The issue can best be explained by Earnshaw’s Theorem, which states that it's not possible to create a spot of maximum magnetic field strength in an empty space and that the strength of a magnetic field decreases with distance from the magnet.

  2. 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 →
  3. 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 →
  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. 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 →
  6. 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 →
  7. 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 →
  8. 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 →
  9. Magnetic Sweepers and Parking Lot Maintenance

    Magnetic Sweepers and Parking Lot Maintenance
    Many business owners have to maintain a parking lot — it’s a responsibility that is often forgotten amidst the long list of other tasks and to-dos. This task shouldn’t be taken lightly though — as long as you own your lot, it’s your job to make sure it’s clean and accessible, whether you do the cleanup yourself or hire workers to come in and do it for you.

  10. Our Solar System’s Magnetic Bubble Resembles an Interesting Food

    Our Solar System’s Magnetic Bubble Resembles an Interesting Food
    All of the planets in the solar system are encased in a magnetic bubble. For years, scientists tried to figure out what this bubble looked like, but it’s been hard to measure because the closest point is more than ten billion miles from Earth. By using a model developed with data from NASA missions, scientists have developed a new prediction of the shape of the bubble surrounding our solar system —  and you might be just as surprised as they were to find it looks a lot like a croissant.  Continue reading →
