Rogowski coil

[rə′gäv·skē ‚kȯil]
(engineering)
A device for measuring alternating current without making contact with the current-carrying conductor, which consists of an air-core coil placed around the conductor in a toroidal fashion so that the alternating magnetic field produced by the current induces a voltage in the coil.
