What is the essential difference between pure iron and silicon steel sheet?
The magnetic properties of the material vary greatly. The silicon steel sheet can form more magnetic flux at the same magnetomotive force.
The silicon steel sheet can reduce the eddy current and reduce the core loss.
There is a great difference in hysteresis properties of the material. The silicon steel sheet has a perfect hysteresis loop, and the electromagnetic induction efficiency is high.
Permeability is very low (less than 1000 Gauss) and high (more than 6000 Gauss) difference.
