    • Abstract


      Definitions of current density and kinetic energy density, for a general many-electron system in the presence of an external magnetic field, are carefully discussed and various results are established. In particular, the electronic energy expression has a purely classical interpretation in which every element of the ‘charge cloud’ behaves like a small magnet, the magnetization depending on the circulation of the induced currents.
