Eddy Current Insights

What is Eddy Current?

Eddy currents are loops of electrical current induced within a conductor by a changing magnetic field in the conductor, according to Faraday's law of induction. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. They are commonly used in non-destructive testing (NDT) to detect surface and subsurface flaws in conductive materials, in eddy current brakes to slow down moving objects, and in induction heating to heat conductive materials.
