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 [...]

Magnetic filters are specialized devices that capture and remove fine iron impurities from fluids, semi-fluids, powders, and gaseous materials. They use the power of magnetism to help keep products pure and protect downstream equipment. Magnetic filters are used in a wide range of industries. You can find them in the [...]

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 [...]

High-performance Neodymium (NdFeB) magnets are made by balancing several things: remanence (Br), intrinsic coercivity (Hcj), and maximum energy product ((BH)max). These are important because we want to make magnets that have strong magnetic fields, don’t demagnetize, and use energy well. As people use more and more magnets in things like [...]

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 [...]

 In the world of magnetic applications, specifically electric motors and transformers, it’s important to understand what the magnetic fields are doing with their surroundings. One of the things that affects magnet performance is the generation of eddy currents. Eddy currents change how magnetic systems work, and they also present opportunities [...]

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, [...]
