Permanent magnets, like those in speakers, motors, and fridge magnets, can retain their magnetism for decades—sometimes even centuries. But how do they resist demagnetization so effectively? The answer lies in their material composition, atomic structure, and resistance to external forces. 1. High Coercivity – Resistance to Demagnetization Coercivity measures how well a magnet resists losing […]

Introduction AlNiCo magnets, made from aluminum, nickel, and cobalt, are one of the oldest types of permanent magnets. Despite the rise of rare-earth magnets like neodymium, AlNiCo magnets continue to play a vital role in various everyday applications. Their high magnetic strength, temperature stability, and corrosion resistance make them indispensable in many fields. In this […]
Demagnetization curve is more accurate for AlNiCo magnetism than Gaussmeter. Why Gaussmeter cannot accurately measure AlNiCo magnetism？ Demagnetization field effect：AlNiCo magnets have high coercivity and low remanence, so they are easily affected by the demagnetization field during measurement. This causes the Gaussmeter to underestimate the actual magnetic field strength. Anisotropy：AlNiCo magnets are highly anisotropic, which […]
