Ceramic magnets, also called ferrite magnets, were developed in the 1960s as a low-cost alternative to metallic magnets. They consist mainly of iron oxide and strontium carbonate. Ceramic magnets are corrosion-resistant and have a high resistance to demagnetization. They’re used in many industries because they’re cheap per pound and hold [...]

How Magnetic Filters Work Magnetic filters use strong magnetic fields to capture and remove metal particles from fluids. Unlike conventional filters that rely on physical barriers like meshes or screens, magnetic filters attract contaminants magnetically, preventing them from passing through the system. Basic Principles of Magnetic Filtration Magnetic Attraction: Ferrous [...]

Neodymium magnets, also known as NdFeB magnets, are among the strongest permanent magnets available today. Despite their exceptional magnetic strength, these magnets are prone to corrosion due to their high iron content. To preserve their structural integrity and extend their lifespan, various coatings are applied to protect them from environmental [...]

Magnetic moments are a fundamental property of particles, atoms, and materials that describe the strength and direction of their magnetic fields. They play a crucial role in understanding how magnetic materials interact with external magnetic fields, and they have many important technological and scientific applications. In this article, we will [...]

Permanent Magnet Generators (PMGs) are innovative machines that convert mechanical energy into electrical power using permanent magnets to generate a magnetic field. Unlike traditional generators that rely on external power sources or induction mechanisms, PMGs leverage the intrinsic properties of permanent magnets, resulting in higher efficiency, lower maintenance, and broader [...]

Basics of Grain Boundaries in Materials In crystalline materials, atoms are arranged in a highly ordered repeating pattern called a crystal lattice. However, these materials are rarely a single crystal. Instead, they consist of many small crystals called grains. Each grain has its own crystal orientation, and the regions where grains [...]

Magnetic anisotropy means that a material has a preferred direction for its magnetic moments when you apply a magnetic field to it. In simpler terms, it means that the way a material is pointed affects how it behaves magnetically. Some materials want to be magnetized more in one direction than [...]

If you’ve ever wondered what is an Eddy current magnet and why it matters in today’s cutting-edge industries, you’re in the right place. This powerful device leverages Eddy currents—those swirling electrical currents in conductors—to create magnetic effects without physical contact. Understanding how these magnets work can unlock new possibilities in applications like braking [...]

After a few years of use, the seal on your refrigerator door might start to lose its magnetism. When this happens, it can cause problems with sealing and keeping the temperature inside your refrigerator where it needs to be. A weak seal can lead to poor energy efficiency, spoiled food, [...]
