Practicing Success
A magnet is moved towards a coil (i) quickly (ii) slowly, then the induced EMF is : |
Larger in (i) Larger in (ii) Same in both Depends upon the radius of the coil |
Larger in (i) |
Faraday's Law : Whenever a conductor is placed in a varying magnetic field, an electromotive force is induced. If the conductor circuit is closed, a current is induced, which is called induced current. |
