  1. Magnets in the Airline Industry

    Magnets in the Airline Industry
    From preventing punctured tires to sorting cutlery, industrial magnets play an important role in the airline industry. Magnets are used in ways that you wouldn’t expect! Without magnets, there could be more problems and overspent budgets.  Let’s look closely at the specifics! Continue reading →
  2. Aquatic Robot Activated by Magnets

    Aquatic Robot Activated by Magnets
    In an article published in the journal Science Robotics, the world was introduced to a new type of robot, one that can move underwater. Researchers at Northwestern University demonstrated how they used magnetic and light fields to make a robot not only walk underwater, but break dance as well. Continue reading →
  3. 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.

  5. 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.

  6. 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 →
  7. 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 →
  8. 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 →
  9. The "Dent" in Earth's Magnetic Field

    The "Dent" in Earth's Magnetic Field
    A dent is evolving within Earth’s Magnetic Field, and it has scientists watching closely. This isn’t necessarily new news though. Scientists have known about this weak spot for decades now, but it’s of importance right now due to one crucial factor-- it’s apparent growth.  This weak spot phenomenon is called The South Atlantic Anomaly (SAA) and it stretches across the Atlantic Ocean from South Africa into Brazil. In this area, the magnetic field is weaker than normal, resulting in a “dent.” The Earth’s magnetic field, also known as the geomagnetic field, is important as it protects us against solar windー a flow of charged particles that are released from the upper atmosphere of the Sun.   Continue reading →
  10. A New Way to Measure Magnets on the Atomic Level

    A New Way to Measure Magnets on the Atomic Level
    When it comes to magnetic materials, magnetic ordering — simply put, the characteristic by which spins within atoms order themselves to allow magnets to interact — is very important to understand.  Recently, a team of researchers created a way to examine electronic spins within magnets at almost the atomic level, showing promising potential in small-level magnetism, like within data storage devices.  Continue reading →
