Controlling DC permeability in cast steels - ScienceDirect

WebThe permeability of a material changes with the amount of magnetic flux forced through it. The specific relationship of force to flux (field intensity H to flux density B) is graphed in a form called the normal magnetization curve. WebImaging the conductivity (permeability) is not a constant value but a function of voltage (H). When it reaches saturation, the iron core conductivity to magnetic flux diminishes from a very high value to that of air.
