Answer:
Faraday
observed that when magnetic flux associated with a coil was changed, a current
was induced in the coil.
He found that when there was relative motion
between a circular coil and a bar magnet, the galvanometer
connected to the coil showed deflection. (1)
The direction of deflection reversed when the direction of
relative motion of magnet was reversed.
No current was induced when the coil and magnet were
stationary with each other. (1)
