"Web5 mrt. 2024 · B = μ 0 H + M so that the magnetization would be the excess of B over μ 0 H. The equation B = μ 0 H + M, would be analogous to the familiar D = ϵ o E + P and the magnetization would then be expressed in tesla rather than in A m -1. This viewpoint does indeed have much to commend it, but so does B = μ o ( H + M). " - How is magnetic permeability measured
