In the equations of classical magnetohydrodynamics, the displacement current is considered
vanishingly small due to low plasma velocities. For velocities comparable to the speed of light, the
full relativistic electromagnetic equations must be used. In the absence of gravitational forcings
and with an isotropic Ohm’s law, it is proved that for poloidal magnetic field and velocity and
toroidal electric field, the electric and magnetic energies tend to be equivalent in average for large
times. This represents a partial extension of Cowling’s theorem for axisymmetric fields.
