Difference Between Isotropic Magnet and Anisotropic Magnet
August 10, 2022

Have you heard of isotropic magnets and anisotropic magnets? What are the connections and differences between them? In simple terms, magnetic materials fall into two categories.

One is an isotropic magnet, which has the same magnetic properties in any direction and can be magnetized in any direction.

The other type is anisotropic magnets. Anisotropic magnets have different magnetic properties in different directions. Only the fixed direction has strong magnetic properties. The direction in which it can obtain the best magnetic properties is called the orientation direction of the magnet, and the magnetic field strength in the orientation direction is the largest ,the magnetic field strength in other directions is much smaller. This type of magnet has high magnetic energy after magnetization and can be used for high torque motors.

Let's take the hot NdFeB magnets as an example. Bonded NdFeB magnets are both isotropic and anisotropic; sintered NdFeB magnets are generally anisotropic magnets, because most of them are formed and pressed by magnetic field orientation. We usually say that if there is an orientation process in the production process, it is an anisotropic magnet. In essence, in the process of magnet processing, a magnetic field is added to magnetize to make the molecules form anisotropic. Our factory produces all kinds of office magnets, motor magnets. Whether you are looking for isotropic or anisotropic magnets, we can do it for you.
