Current instability and turbulence in metals

Magnetodynamical instability of pulse electric current flowing in metal pla te in parallel to external magnetic field is studied both theoretically and experimentally. a set of equation is presented for the alternating magneti c field inside the plate. The condition of the instability threshold is der ived. The possibility to transfer into the chaotic oscillations of current above the threshold is shown. The oscillations become turbulent if the puls e current magnitude far exceeds the threshold value.
