What Are The Three Subcategories of Magnetic Materials
There are several subcategories of magnetic materials, including soft magnetic materials, hard magnetic materials, and superconducting materials, each with its own unique properties and applications.
Soft Magnetic Materials
Soft magnetic materials, such as silicon steel, have a high magnetic permeability and are used in applications where a strong magnetic field is needed, but where the magnetic field needs to be easily controlled.
Hard Magnetic Materials
Hard magnetic materials, such as rare earth magnets, have a high magnetic coercivity and are used in applications where a strong, permanent magnetic field is needed.
Superconducting materials are materials that can conduct electricity with zero resistance and are used in a wide range of applications, including particle accelerators and MRI machines.
