Question

what is induction

Answer 1

Induction (from Latin word meaning "I lead") in physics is a process of making something to emerge by an indirect influence.

For instance, consider the electromagnetic induction. When you move a piece of metal above a magnet or vice versa, an electric current flows in the metal. This is the way electrical generators and transformers work.

The electrostatic induction occurs when an object is located in area where electric charges are present. For example, if you are approach an electrically charged rod (or a balloon) to an electroscope, its leaves separate from each other.

As we see, to make an induction occur, we do not need to directly interact with the body subjected to induction.
