Define electrostatic charging by induction.

It is a process in which electrical charges are redistributed in a neutral body by bringing an electrically charged object near to it.

Note: This type of induction is most effective in electrical conductors, but can also happen in some electrical insulators.

A metal plate being induced with a positive charge near the top surface, and a negative charge near the bottom surface.

Better still, test it out yourself! 🙂
