Detailed Solution

The factors on which the value of induced current in a coil in the presence of magnet depends on are the number of turns in the coil , the strength of the magnet used and the speed with which magnet is pushed into the coil.
Here, we know that the magnitude of the induced current is determined by the rate at which the magnetic flux changes. So, as the number of turns rises, so does the size of the induced current. Also, the magnitude of the induced current rises as the speed of the magnet's relative motion rises. Since the size of the produced current increases, so does the magnet's strength.
