| inductive current drive | <physics> Method to drive current in a toroidal plasma by using the torus of conducting plasma as the second coil in a transformer. The primary coil usually runs down the centre of the torus, changes in the current driven through the primary coil create changing magnetic fields which drive current in the plasma. The current thus driven can be used to heat the plasma as well (see also ohmic heating, induction). (09 Oct 1997) |

| Tesla current | An alternating electric current having a frequency of 10,000 or more per second; it produces no muscular contractions and does not affect the sensory nerves. Synonym: d'Arsonval current, Tesla current. (05 Mar 2000) |
| eddy current | <radiobiology> Electric current induced inside a conductor when the conductor (a) moves through a nonuniform magnetic field, or (b) experiences a change in the magnetic flux through its surface. (09 Oct 1997) |
| eddy-current loss | <radiobiology> Energy loss due to eddy currents circulating in a resistive material. (09 Oct 1997) |
| toroidal current | <radiobiology> Current flowing in the toroidal direction (the long way) around a torus. (As distinct from poloidal currents flowing through the centre of the torus and around to the outside, the short way.) (09 Oct 1997) |
| labile current | An electrical current applied to the body by means of electrodes that are constantly shifted about. (05 Mar 2000) |
