Tesla|ˈtɛzlə|
[The name of Nicola Tesla (1856–1943), Croatian-born American electrical physicist.]
1. Tesla coil, a type of induction coil invented by Tesla, employing a spark gap in place of an interruptor and capable of producing an intense high-frequency discharge.
1896Amer. Jrnl. Sci. CLI. 245 By changing the size of the spark gap in the primary circuit of the Tesla coil one has a great range of electrical energy at command. 1930Proc. R. Soc. A. CXXIX. 479 If it is desired simply to obtain the highest possible potentials with the minimum of trouble then the Tesla coil is obviously the ideal solution. 1975Bio Systems VII. 6/2 Thus far, energy has only been fed in by sparking electrodes kept at roughly controlled voltage level with Tesla coils.
2. Physics. (Usu. with small initial.) Pl. tesla, teslas. The SI unit of magnetic flux density, equal to one weber (weber) per square metre; 10,000 gauss. Symbol T.

June 36/3 The oscillating magnetic field in the radio pulse itself as it leaves the pulsar is probably greater than 10 teslas (105 gauss). 1971New Scientist 24 June 737/2 Superconductors cannot yet sustain fields greater than 12 Tesla. 1980J.
