Everyone knows that there are many types and applications of soft magnetic materials. So what are the main characteristics of soft magnetic materials properties?
Soft magnetic materials have 5 main magnetic properties:
One of the soft magnetic materials properties is that they have high magnetic permeability. Magnetic permeability (with symbol μ) is a measure of sensitivity to magnetic fields.
The soft magnetic material is not only easy to be magnetized by the external magnetic field, but also easy to be demagnetized by the external magnetic field or other factors. Its magnetic loss is also low.
The soft magnetic material has high saturation magnetic flux density (bs) and saturation magnetization (ms). In this way, it is easier to obtain high permeability (μ) and low coercive force (Hc), which can also increase the magnetic energy density;
The magnetic loss and electrical loss of soft magnetic materials is low. It requires low coercivity (Hc) and high resistivity;
The soft magnetic materials have high stability. It requires the above-mentioned soft magnetic materials properties to be stable enough to against environmental factors such as temperature and vibration.
