What is Permeability?
Permeability: This is defined as the ability of the material to conduct flux. This is defined as the ratio of magnetic flux 'B' in a medium to the magnetic flux intensity 'H' at similar location in the medium, that is µ = B/H, here B is plotted against H, a curve is acquired, called magnetization curve or B-H curve. The permeability of any material is not a constant. This permeability at low value of H is termed as initial permeability. The common core materials as low carbon steel, silicon steel contain low initial permeability.
