Would you like to make it the primary and merge this question into it?

#### exists and is an alternate of .

When a pice of magnet shuttles through a loop of conductor (copper wire) it induces electric energy in the conductor, this is known as induction. When alternating current (AC) or interrupted DC current applied to the primary winding of a transformer, the magnetic flux cutting through the secondary known as conduction produces electric power in the secondary. The ratio of power gained or lost in the secondary winding depends on the ratio of turns of conductor between primary and secondary. Newaz.
