Abstract
The vacuum dynamics of SU(2) lattice gauge theory is studied by means of a gauge-invariant effective action, both at zero and finite temperature. Work ing with lattices up to 32(4) we check the scaling of the energy density wi th the magnetic length. We find that the screening at zero temperature of t he applied external magnetic field weakens by increasing the temperature.
