Magnetic induction was discovered by Michael Faraday.
He discovered that moving a magnet near a wire will cause current to flow through the wire.
There are lines of magnetic flux surrounding a magnet. As the magnet is moved near the wire the lines of flux from the magnet react with the electrons in the wire and result in a current flow. You can demonstrate this by duplicating some of Faraday's early experiments.
Refer to the picture:
As long as the magnet stays stationary you should see no current flow.
As you move the magnet forward you will see flow in one direction depending on the poles of the magnet.
As pull the magnet back the direction of flow should reverse.
The faster you move the magnet the stronger the current will become.
