Faraday’s
Law of ElectroMagnetic Induction
Both the laws of e.m.i. can be combined into a single mathematical statement.
and, if the conductor is a coil having N turns, we have:
This is often known as Neumann’s Law. In the case of a straight conductor moving at 90° to a uniform field, we found
If the conductor moves a distance s in time t, then the speed, v, is given by v = s/t. Therefore, the induced emf is given by
So, in this case, the two statements are equivalent.
