What is the definition of eddy current loss?

Eddy currents (also called Foucault currents) are loops of electrical current induced within conductors by a changing magnetic field in the conductor, due to Faraday's law of induction. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. read more

Similar to hysteresis loss, eddy current loss also increases the temperature of the magnetic material. The hysteresis and the eddy current losses in a magnetic material are also known by the name iron losses or core losses or magnetic losses. A sectional view of the magnetic core is shown in the figure above. read more

Eddy-current loss definition is - loss of energy (as in electrical machinery or transformers) due to eddy currents in cores or conductors. read more

Eddy currents are the root cause of the skin effect in conductors carrying AC current. Lamination of magnetic cores in transformers greatly improves the efficiency by minimising eddy currents Similarly, in magnetic materials of finite conductivity eddy currents cause the confinement of the majority of the magnetic fields to only a couple skin depths of the surface of the material. read more
