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.
