Did you know?
WebWhat is magnetic permeability? Magnetic permeability is defined as the ratio of the magnetic induction to the magnetic intensity.It is a scalar quantity and denoted by the symbol μ. Magnetic permeability helps us measure a material's resistance to the magnetic field or measure of the degree to which magnetic field can penetrate through a material. WebFerromagnets with high retentivity and coercivity are used as permanent magnets (hard magnets), while the ones with low retentivity & coercivity (soft magnets) are used as cores in electromagnets. But all ferromagnets have high permeability.
