where μ 0 is the permeability of free space and M is the volume magnetization. In the absence of an external magnetic medium, the H-field lines are identical to B-field lines outside a magnet (the stray field) and only differ by a factor μ 0, (B = μ 0 H); but inside they point in a different direction. B is solenoidal (∇⋅B = 0), meaning …
