Question

what is induction of charge

Answer 1

"Electromagnetic or magnetic induction is the production of an electromotive force( i.e., voltage) across and electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James clerk Maxwell mathematically described it as Faraday's law of induction. "

Answer 2

There are a variety of methods to charge an object.One method is known as Induction.In the induction process, a charged object is brought near but not touched to a neutral conducting object. The presence of a charged body near a neutral conductor will force(or induce) electrons within the conductor to move.
