Ímãs de cerâmica, 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 […]
Filtros magnéticos usam campos magnéticos fortes para capturar e remover partículas metálicas de fluidos. Diferentemente dos filtros convencionais que dependem de barreiras físicas como malhas ou telas, os filtros magnéticos atraem contaminantes magneticamente, impedindo que eles passem pelo sistema.
Ímãs de neodímio, 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 […]
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 […]
Em materiais cristalinos, os átomos estão organizados em um padrão repetitivo altamente ordenado chamado rede cristalina. No entanto, esses materiais raramente são um cristal único. Em vez disso, eles consistem em muitos pequenos cristais chamados grãos. Each grain has its own crystal orientation, and the regions where […]
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 […]
Se você já se perguntou o que é um ímã de corrente de Eddy e por que isso importa nas indústrias de ponta de hoje, você está no lugar certo. Este dispositivo poderoso aproveita Correntes de Eddy—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, […]
Magnets, whether they’re used in industrial applications or in products you have around the house, create a magnetic field that can be more or less strong. Knowing how to measure this strength is important, especially when you use magnets in applications where reliability and performance are critical. In this guide, […]
