pinch effect

pinch effect
the tendency of an electric conductor or stream of charged particles to constrict, caused by the action of a magnetic field that is produced by a flow of electricity.
[1905-10]

      self-constriction of a cylinder of an electrically conducting plasma. When an electric current is passed through a gaseous plasma, a magnetic field is set up that tends to force the current-carrying particles together. This force can compress the plasma so that it is heated as well as confined, but such a self-pinched plasma cylinder is unstable and will quickly develop kinks or break up into a series of lumps resembling a string of sausages. The pinch effect, therefore, must be augmented with other magnetic-field configurations to produce a stable magnetic bottle.
