1. The result of an electromechanical force that constricts, and sometimes momentarily ruptures, a molten conductor carrying current at high density. </dd>
2. The self-contraction of a plasma column carrying large currents due to the interaction of this current with its own magnetic field. </dd>
The current required for such an effect is the order of 10E5 amperes. If the current is pulsed on for a short time, a radially imploding shock wave is generated. </dd>
