Application of High Magnetic Permeability Soft Ferrite Material
According to the soft magnetic definition, a soft magnetic material is generally referred to as all low coercivity magnetic materials. Soft magnetic materials widely used in various electronic devices include metal soft magnetic materials, amorphous soft magnetic materials, and ferrite soft magnetic materials. In contrast, the magnetic permeability of metal soft magnetic material is the highest, the magnetic permeability of amorphous soft magnetic material is medium, and the ferrite soft magnetic material is the lowest. However, on the contrary, the metal soft magnetic material has the lowest resistivity, the amorphous soft magnetic material has the middle resistivity, and the ferrite soft magnetic material has the highest resistivity. Therefore, metal soft magnetic materials are generally used in low-frequency electronic devices, amorphous soft magnetic materials are used in intermediate frequency devices, and ferrite soft magnetic materials are often used in high-frequency devices. Soft ferrite is very widely used, it has a very close relationship with our daily life in communications, automatic control and computing technology, etc.
