  1. Magnets in Electronics

    Magnets in Electronics
    We use our state-of-the-art cell phones, tablets and televisions on a regular basis, but it’s easy to forget about the parts inside that make them work so well and allows them to be a fixture in our lives. As it turns out, a lot of the electronics we use every day rely on magnets to function at their fullest capability. We’ll show you how. Continue reading →
  2. How Electromagnets are the Driving Force Behind Cranes

    How Electromagnets are the Driving Force Behind Cranes
    A crane is one of the most important forms of industrial equipment in the construction, automotive and manufacturing industries. Skyscrapers, apartment complexes and other massive man-made structures cannot be built without them, while steel storage crates containing cars or manufacturing machines rely on cranes to be placed onto ships before they are transported overseas. Did you know that cranes wouldn’t be able to function without electromagnets? Below, we’ll explore exactly how these electromagnets act as the driving force behind industrial cranes.

  3. Magnetic Sense Helps Moths in Migration

    Magnetic Sense Helps Moths in Migration
    To escape the inevitable summer heat, Bogong moths migrate every spring from Queensland, New South Wales and Victoria to the meadows of the Australian Alps. Once their journey is complete, they congregate in caves and go dormant for summer, similar to hibernation. Upon Autumn’s arrival, these insects return to their birthplaces, mate, lay eggs, and die. The eggs turn into caterpillars that develop underground throughout the winter, and the cycle continues indefinitely. Continue reading →
  4. Pyramid of Giza and Its Electromagnetism

    Pyramid of Giza and Its Electromagnetism
    Ah, the Great Pyramid of Giza. The oldest and last remaining Wonder of the Ancient Worlds. Just when we thought that we were perplexed enough about this structure, its engineering and construction, and its size and proportions, scientists recently married physics and pyramid research to discover a connection between the pyramid’s structure and electromagnetism.

  5. Laser-Generated Magnets: A Third Option to Permanent Magnets and Electromagnets

    Laser-Generated Magnets: A Third Option to Permanent Magnets and Electromagnets
    Permanent magnets are wonderful tools, but they do have an inherent drawback, depending on your application: They’re always working. Unless a rare earth magnet gets too hot or is demagnetized by a nearby force, it will continue generating a magnetic force indefinitely. Continue reading →
  6. The Use of Magnetic Separators in the Mining Industry

    The Use of Magnetic Separators in the Mining Industry
    The mining industry requires some powerful machinery – draglines, excavators, and massive drill rigs. You’ve likely seen one or more these machines while driving down the highway. It is a tough line of work that employs equally tough people, but as demanding as the industry is, and as imposing as most of the machinery tends to be, it requires other, more delicate equipment as well.  Continue reading →
  7. Electromagnetic Spider Webs

    Electromagnetic Spider Webs
    While this Apex blogger is certainly not a fan of spiders, we have to agree that they are fascinating creatures. The eight-legged arthropods spin their silk webs and perch, waiting for their prey to fall at their doorstep. You probably assume that a spider’s prey lands in a web by happenstance, but it has been recently discovered that spiders have a few hidden electromagnetic tricks for trapping their prey.

  8. Hyperloop Hotel: Travel in Magnetic Luxury

    Hyperloop Hotel: Travel in Magnetic Luxury
    We’ve talked about the Hyperloop previously on the blog, but just in case you’re not up to speed, we’ll give you a little refresher. Presented in 2013 by Elon Musk, the Hyperloop is a proposed low-pressure tube system powered by electromagnetism. It would be capable of spanning longer distances in less time than has ever been possible. Imagine being able to travel from Los Angeles to San Francisco (350 miles) in under 35 minutes. Cross-country travel would be changed forever, and for the better! Continue reading →
  9. Look Ma, No Hands: A Look into Wireless Charging

    Look Ma, No Hands: A Look into Wireless Charging
    With Samsung, Google, and Microsoft already utilizing inductive, or wireless charging, rumor has it that Apple’s next iteration of the iPhone will include their own take on the charging method. Setting your phone down on a tiny dock and not worrying about having to plug it in to charge it might seem like magic to some, but it’s a very real possibility in 2017. Continue reading →
  10. Delicate Sound of Thunder: Exploring Electromagnetic Whistlers

    Delicate Sound of Thunder: Exploring Electromagnetic Whistlers
    When we think of lightning storms, we usually associate them with scary, booming claps of thunder. These audible bursts are caused by a sonic shockwave as lightning discharges. However, thunder is not the only sound of the storm. High above the clouds, in the farthest reaches of our atmosphere, another symphony is taking place. This is the concert hall of the electromagnetic electron wave, also known as a whistler. Continue reading →
