Q. What do you mean by Induction?
The essentials for producing an emf bymagneticmeans are electric andmagnetic circuits,mutually interlinked. Figure (a) shows a load (or sink or motor) convention with the induced emf (or back emf) e directed in opposition to the positive current, in which case Faraday's law of induction,
applies, where λ is the flux linkages, N is the number of turns, and φ is the flux. On the other hand, the induced emf e (or generated emf) acting in the direction of positive current, as shown in Figure (b) with a source (or generator) convention, satisfies Faraday's law of induction,
