What is induced current and what is its direction?
The relative motion of the magnet or a coil induces a p.d between the terminals of a coil and sends a current in the external circuit is called electro magnetic induction. The resulting current is called induced current.
The direction of induced current is explained by Fleming's right hand rule. Stretch the forefinger, central finger and thumb of our right hand mutually perpendicular to each other. Then, the forefinger shows the direction of the magnetic field, thumb shows the direction of motion and the central finger shows the direction of induced current.
The phenomenon by which the charge in the magnetic field in one set of coil induces a current in another set of coil nearby is called electro magnetic induction discovered by Michael Faraday.
