Magnetic Properties of Materials

Magnetic Properties of Materials: Magnetic Properties of Materials – From the magnetic point of view a material is classified according to the nature of its relative permeability (μr). All nonmagnetic materials are classified as paramagnetic ,μr slightly greater than 1, and diamagnetic, μr slightly less than 1. For all practical purposes, μr of these materials […]

BH Curve Relationship

BH Curve Relationship of Magnetization Characteristic: In free space (also nonmagnetic materials), the permeability μ0 is constant so that BH Curve Relationship is linear. This, however, is not the case with ferromagnetic materials used in electric machines, wherein the BH Curve Relationship is strictly nonlinear in two respects saturation and hysteresis. Hysteresis non-linearity is the double […]
