Magnetic reluctance of materials

WebReluctance - Is the opposition that a ferromagnetic material shows to the establishment of a magnetic field. Reluctance is analogous to the resistance in an electrical circuit. Relative to other materials, a material with a wider hysteresis loop has: Lower Permeability; Higher Retentivity; Higher Coercivity; Higher Reluctance; Higher Residual ...
