Soft magnetic material
Soft magnetic material Soft magnetic materials refer to when the magnetization occurs at Hc not greater than 1000A/m, such materials are called soft magnetic materials. Typical soft magnetic materials can achieve maximum magnetization with the smallest external magnetic field. Soft magnetic material (soft magnetic material) A magnetic material with low coercivity and high permeability. Soft magnetic materials are easy to magnetize and demagnetize, and are widely used in electrical and electronic equipment. The most commonly used soft magnetic materials are iron-silicon alloy (silicon steel sheet) and various soft ferrites. Soft ferrite The characteristics of soft ferrite are: low saturation magnetic flux density, low permeability, low Curie temperature, low medium and high frequency loss, and low cost. The first three lows are its shortcomings, which limit its scope of use. Now (the beginning of the 21st century) is working hard to improve. The latter two lows are its advantages, whic
