Eddy Current Applications Class 12. Eddy currents (also called Foucault currents) are currents induced in conductors, when the magnetic flux linked with a solid conductor changes. The change in magnetic flux can cause a circulating flow of electrons, or a current, within the body of the conductor. The term eddy current comes […] Eddy currents are the currents induced in a metallic plate when it is kept in a time varying magnetic field. Magnetic flux linked with the plate changes and so the induced current is set up. Eddy currents are sometimes so strong, that metallic plate becomes red hot. Applications: In induction furnace, the metal to be heated is placed in a rapidly varying magnetic field produced by high. History. Eddy current testing (ECT) as a technique for testing finds its roots in electromagnetism. Eddy currents were first observed by François Arago in 1824, but French physicist Léon Foucault is credited with discovering them in 1855. ECT began largely as a result of the English scientist Michael Faraday's discovery of electromagnetic induction in 1831.

Applications of Eddy Current Brakes For additional safety on long decants in mountain area For high speed passenger and goods vehicle. Eddy current brakes are best substitutes for ordinary brakes, which are being used nowadays in road vehicles even in trains, because of their jerk-free operation. In mountain areas where continuous braking force. Eddy currents are the currents induced in a metallic plate when it is kept in a time varying magnetic field. Magnetic flux linked with the plate changes and so the induced current is set up. Eddy currents are sometimes so strong, that metallic plate becomes red hot.
