Why is it important to choose the micro-magnetic valve soft magnetic material?

Several criteria for the selection of micro-magnetic valve soft magnetic materials:
1. GB/T 14986-2008 《High Saturation, Magnetic Temperature Compensation, Corrosion Resistance, Ferro-aluminum, Constant Magnetic Conductivity Soft Magnetic Alloy》
2. GB/T 13012-2008 "Measuring Methods for Magnetic Properties of Soft Magnetic Materials"
3, GB/T 3658-2008 "soft magnetic materials AC magnetic properties of the ring specimen measurement method"
4. GB/T 13888-2009 Method for Measuring Coercive Force of Magnetic Material in Open Magnetic Circuits
5. IEC 60404-8-6:1999 "Soft Magnetic Metal Materials"
The importance of the selection of soft magnetic materials for miniature solenoid valves:
Electromagnets generally use soft magnetic materials, and different soft magnetic materials have great differences in magnetic properties.
The magnetically conductive material has a high resistivity, and the high resistivity can improve the high frequency performance and reduce the eddy current loss; the magnetically coercive material has less coercive force, and the small coercive force indicates that the magnetic hysteresis loop has less area and less iron loss. The residual magnetic induction of the magnetic material should be low, and the low residual magnetic induction can reduce the release time of the moving iron core; the saturation magnetic induction of the magnetic material should be high, and the high saturation magnetic induction can increase the electromagnetic force of the electromagnet; High conductivity, high permeability can reduce response time.
