Maximum Operating Temperature VS. Curie Temperature
Introduction Magnets are materials that generate a magnetic field and have the ability to attract or repel other magnets or ferromagnetic materials. They are commonly used in a wide range of applications, such as in electric motors, generators, speakers, and magnetic sensors. However, magnets can lose their magnetic properties at high temperatures, which is an

General Information About AlNiCo Magnets
AINiCo magnets are a special type of magnet mainly composed of aluminum, nickel, and cobalt. These magnets can also include titanium, iron, and copper. They come in two forms; the isotropic, non-directional form, or the anisotropic, mono-directional form. Once they’re magnetized, they typically have 5 to 17 times the magnetic force of magnetite or lodestone. These

Rare Earth Permanent Magnet Motors
Rare Earth Permanent Magnet Motors As early as the 1820s, the world’s first motor appeared, and the rotor of this motor is a permanent magnet to generate an excitation magnetic field. However, the permanent magnet material used at that time was natural magnetite (Fe3O4), which had a very low magnetic energy density. The motor made from

Rare Earth Magnet Types and Uses
Rare Earth Magnet Types and Uses Rare earth magnets refer to powerful permanent magnets composed of rare earth element alloys. Among permanent magnets, rare earth magnets can generate the largest magnetic field, which is much larger than that of AlNiCo magnets or ferrite magnets. Rare earth magnets can generally generate a magnetic field exceeding 1.4 Tesla, while

Precautions for Using Lifting Magnets
Precautions for Using Lifting Magnets Lifting magnets are often used in some metal processing and large machinery manufacturing companies for lifting, loading, unloading, and transportation operations. At present, common lifting magnets include lifting electromagnets, lifting electro-permanent magnets, and permanent magnets. Regardless of the type, some operating rules related to lifting magnets must be observed. So in this
