Ferromagnetic substances can be magnetized to saturation as long as they are under the action of a small magnetic field. Not only the magnetic susceptibility is >0, men tou valè a se gwo kòm 10-106 lòd grandè. Relasyon ki genyen ant mayetizasyon M a ak jaden mayetik H a se yon fonksyon konplèks ki pa lineyè. relasyon.
