Electromagnetic Fields and Waves
... An electro-motive force is a voltage that arises from conductors moving in a magnetic field or from changing magnetic fields. 2. State Faraday’s law. Faraday’s law states that, the total emf induced in a closed circuit is equal to the time rate of decrease of the total magnetic flux linking the circ ...

... induction of the magnetic material. This effect of retardation by material is called hysteresis. The magnetic field strength needed to bring the induced magnetization to zero is termed as coercivity, Hc. This must be applied anti-parallel to the original field. A further increase in the field in ...
