WebEddy Currents and Magnetic Damping. As discussed in Chapter 23.3 Motional Emf, motional emf is induced when a conductor moves in a magnetic field or when a magnetic field moves relative to a conductor.If motional emf can cause a current loop in the conductor, we refer to that current as an eddy current.Eddy currents can produce … WebJan 22, 2024 · Eddy currents (also called Foucault currents) are loops of electrical current induced within conductors 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.

WebNote:- In a moving coil galvanometer, damping is necessary to avoid oscillation of display needle. This is brought into practice with the help of eddy currents. The winding of the coil of galvanometer is done on a metallic frame. When the coil rotates the magnetic flux linked with the metallic frame changes due to which eddy currents are developed which … http://web.mit.edu/viz/EM/materials/faraday/Overview/overview_faraday ct whole spine
