WebApr 6, 2024 · Eddy Current Principle. An eddy current is also called the Foucault current. Eddy currents are swirls of electric currents induced within conductors by a changing magnetic field within the conductor (self-inductance). Eddy current works on the principle of Faraday’s law of induction. The Eddy Current Principle works as the Self-inductance.
