Eddy Current Applications Class 12. As flux changes there is induced current.The direction of the induced current will be opposite to itsmean position. When the induced current leaves the magnetic field, again current will be induced but in the opposite direction. This effect of induced currents together gives the effect of eddy currents.

Eddy Current – Explained. Induced electromotive force is produced in the coil when there is a change in the magnetic flux linked with that coil. Eddy currents are named so because the current looks like eddies or whirlpools. When a conductor is placed in the changing magnetic field, the induced current in the conductor is termed as Eddy currents. 1. There will be total 10 MCQ in this test. 2.

Class 12 Physics Electromagnetic Induction: Eddy currents : Applications: Eddy currents : Applications. Electromagnetic brakes –To control the speed of fast moving electric trains.. This will result in change in flux and induced current will be produced.
Eddy currents (also called Foucault's 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. They can be induced within nearby stationary conductors by a time-varying magnetic field created by an. Electromagnetic Induction Important Questions for CBSE Class 12 Physics Eddy Currents and Self and Mutual Induction. 1.Eddy currents are induced in solid metallic sheets/cylinders, when magnetic flux linked with them changes.Direction of eddy currents can be given by Lenz’s law or by Fleming right hand rule.
