Magnetic Generation due to Mass Difference between Charge Carriers

The possibility of spontaneous magnetization due to the "asymmetry in mass" of charge carriers in a system is investigated. Analysis shows that when the masses of positive and negative charge carriers are identical, no magnetization is predicted. However, if the masses of two species are different, spontaneous magnetic field would appear, either due to the equipartition of magnetic energy or due to fluctuations together with a feedback mechanism. The conditions for magnetization to occur are also obtained, in the form of n-T phase diagram. The theory proposed here, if confirmed by future observations and/or experiments, would provide a new insight on the origin of magnetic fields in the universe.
