Dissipation of electromagnetic energy in conducting media takes
place not only because of its absorption due to acceleration of
charged particles by the electric field and their inelastic
collisions with atoms, but also due to interaction of the wave's
magnetic field with magnetic and electric dipole currents induced
by those collisions in the atoms. The simplest way to describe
this phenomenon is to use Ohm's law for magnetic dipole current as
H. Harmuth suggested in his Modified Maxwell's equations.
