For a core having a relative permeability μr, magnetic dipole moment per unit volume M and field strength H, the flux density B is-A-B = μr (H + M)B-B = μ0 (H + M)C-B = μ0μr (H + M)D-B = μ0μr (H M)-B-B = μ0 (H + M)

Question

For a core having a relative permeability &mu;r, magnetic dipole moment per unit volume M and field strength H, the flux density B is-A-B = &mu;r (H + M)B-B = &mu;0 (H + M)C-B = &mu;0&mu;r (H + M)D-B = &mu;0&mu;r (H M)-B-B = &mu;0 (H + M)
