Soft magnetic materials are those materials that are easily magnetised and demagnetised. They typically have intrinsic coercivity less than 1000 Am-1. They are used primarily to enhance and/or channel the flux produced by an electric current. The main parameter, often used as a figure of merit for soft magnetic materials, is the relative permeability (µr, where µr = B/ µoH), which is a measure of how readily the material responds to the applied magnetic field. The other main parameters of interest are the coercivity, the saturation magnetisation and the electrical conductivity.
Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of steel with silicon (silicon is also called silicon), and its silicon content is 0.8 ~ 4.8%. The reason why silicon steel is used as the iron core of transformer is that silicon steel itself is a magnetic material with strong magnetic conductivity. In the energized coil, it can produce large magnetic induction intensity, which can reduce the volume of transformer.
The common mode inductor using nanocrystalline core material can well suppress the peak voltage, protect sensitive components, and reduce the motor shaft voltage. Because of the unique characteristics of nanocrystalline core, it has been well used in some high-power system industries. Electric energy meter, power meter, ammeter, electric measuring equipment and other instrument fields. Various power current transformers in power transmission and distribution monitoring system. Leakage protection, relay protection, servo motor protection, fire monitoring, etc Current and voltage data sampling, etc.

Amorphous nanocrystalline alloys are competing with soft ferrite in the field of medium and high frequency. In 10kHz to 50KHz electronic transformer, the working magnetic flux density of iron-based nanocrystalline alloy can reach 0.5T and the loss P0.05 5 / 20K ≤ 25W / kg, so it has obvious advantages in high-power electronic transformer. In 50 kHz to 100 kHz electronic transformer, the loss of iron-based nanocrystalline alloy is P0.05 2 / 100k is 30 ~ 75W / kg, Fe based amorphous alloy P0.05 2 / 100k is 30W / kg, which can replace some ferrite markets.
On the one hand, it can isolate eddy current, and the data is suitable for higher frequencies; On the other hand, due to the gap effect between particles, the data has low permeability and constant permeability; Because the particle size is small, there is basically no skin phenomenon, and the change of permeability with frequency is relatively stable; Moreover, the powder core can be prepared into special-shaped parts of various shapes for different fields; Finally, the damaged strip in industry can be crushed into magnetic powder, and then made into magnetic powder core, which can reduce the loss and improve the use value of data. The magnetoelectric properties of magnetic particle core mainly depend on the permeability of powder material, size and shape of powder, filling coefficient, content of insulating medium, forming pressure and heat treatment process.
