Solution

Faraday connected the coil to a galvanometer, and moved the magnet back and forth inside the cylinder. Lenz's law state that the direction of the current induced in a conductor by a changing magnetic field is such that the magnetic field created by the induced current opposes the initial changing magnetic field. Since, the magnetic field is first increasing and then decreasing. Hence, the induced current also changes the direction.

Hence, the induced current in the Faraday's experiment was not DC.
