Transfer of Electron Exergy and Thermal Energy in Magnetic Field

Electrons placed in magnetic field create magnetization currents with kinetic and magnetic energy, which is an important part of the electron exergy. Even in the presence of an external thermal field the magnetization currents are dissipationless and, therefore, they do not produce entropy. However, temperature dependence of magnetization involve the magnetization currents into thermal phenomena in rather sophisticated way, which includes transformations of bulk currents into surface currents and interaction between magnetization currents. We review and revise the transfer of electron exergy and thermal energy in magnetic field, including Poynting vector, Onsager relations, Nernst and Ettingshausen effects in superconductors. Recent experiments with single magnetic vortices directly confirm our theoretical conclusions.
