Eddy Current Testing (ECT)
Eddy currents were identified by James Maxwell in 1864. The term “eddy currents” resulted from the similarity in the movement of these circulating electrical currents to the whirlpool activity of so-called “eddies” in liquids. Eddy currents are defined as circulating electrical currents indirectly induced in an isolated conductor by an alternating magnetic field. The alternating magnetic...
