Magnetic field strength is defined by vector field which has a direction and a magnitude (or strength). The relation between Magnetic strength H and flux density B can be defined by B = μH. μ in this case is permeability, the unit of magetizability. In the air, μis usually about 1, except special case, and 1 Gauss ≒ 1 Oersted.

Permeability, on the other hand, is a measure of how easily a magnetic field can be set up in a material. However, rather than just being a measure of the ratio of the m.m.f. to the flux it produces, permeability takes into account the distribution of the flux within the material. Permeability is the ratio of the flux density of the magnetic ...
