Magnet Facts

Magnets play a critical role in modern agriculture. You may be surprised to learn that magnets are behind many of the systems that support large-scale farming operations.  Whether you're running a livestock operation, managing irrigation infrastructure, or processing harvested crops, there are proven magnetic solutions that can reduce costs, protect equipment, and improve outcomes without complicated installations or heavy maintenance...

While early windmills date back centuries and were primarily used for tasks like pumping water, modern wind turbines are highly advanced systems designed to generate power efficiently and reliably. Today, wind turbines play an important role in global energy production. A single onshore wind turbine can typically power hundreds of homes, while larger offshore turbines, which benefit from stronger and...

The Moon doesn’t have a global magnetic field like Earth, yet scientists have found magnetized rocks scattered across its surface. So where did that magnetism come from? One of the most compelling answers involves meteors and asteroid impacts. Scientists believe meteors help magnetize the moon. When large objects collide with the Moon, they can create conditions strong enough to magnetize...

As 3D printing moves from prototyping to production and tooling, printer design has become increasingly focused on precision, repeatability, and ease of maintenance. Magnets play a critical role inside many modern 3D printers, supporting motion control, alignment systems, and removable components that streamline operation and service. Understanding how magnets are used inside 3D printers helps engineers, manufacturers, and equipment designers...

If you’ve ever heard warnings like “keep magnets away from your computer!” you might wonder whether your fridge magnets or the neodymium magnets in your home can really cause damage. Today, we’re diving into the science behind magnets and data and answering the big question: Can a strong magnet wipe out a hard drive? How Traditional Hard Drives Store Data...

As the year winds down, it’s a fitting time to reflect on the technologies that continue to shape our industries and one of the most powerful forces behind them: magnetism. 1. Magnetic Resonance Imaging (MRI): Revolutionizing Healthcare Technology Magnetic resonance imaging remains one of the most transformative uses of magnetism. Using powerful superconducting magnets, MRI machines generate detailed internal images...

With gold and silver prices hitting record highs, many people are selling or buying precious metals. Whether you’re a coin collector, investor, or simply cleaning out old jewelry, now is the right time to make sure your items are authentic. One of the fastest tests for authenticity is using a magnet. Why Use a Magnet to Test Gold or Silver...

Magnets are everywhere, from the fridge door to your headphones, but have you ever wondered why certain materials are magnetic while others are not? The answer lies in the structure of atoms and the behavior of their electrons. The Science Behind Magnetism Atoms are made up of protons, neutrons, and electrons. Electrons orbit the nucleus and also “spin.” These tiny...

When we think of magnets, rare earth elements like neodymium and samarium cobalt often come to mind. But there’s another metal just as critical to magnetic assemblies: copper. While copper itself isn’t magnetic, its unmatched electrical conductivity makes it indispensable for creating, stabilizing, and optimizing magnetic fields. Why Copper Matters in Magnetism Copper plays a central role in electromagnets, superconductors...

A superconducting magnet is a type of electromagnet built from coils of superconducting wire. When cooled to cryogenic temperatures, these wires conduct electricity with zero resistance, allowing the magnet to generate extremely strong, stable magnetic fields without losing energy as heat. In fact, superconducting magnets can generate fields over 2,000 times stronger than the magnets on your refrigerator!  Superconducting magnets...
