Learning Goal: To understand the terms in Faraday's law and to be able to identify the magnitude and direction of induced emf. Faraday's law states that induced emf is directly proportional to the time rate of change of magnetic flux. Mathematically, it can be written as E=???B?t, where E is the emf induced in a closed loop, and ??B?t is the rate of change of the magnetic flux through a surface bounded by the loop. For uniform magnetic fields the...
