Complete Question

1. In the demonstration where a magnet is brought near a loop, what determines the induced current?

a - the strength of the magnetic field intercepted by the loop

b -  the rate at which the number of magnetic field lines intercepted by the loop  changes

c - the spacing of the magnetic field lines intercepted by the loop

d -  the number of magnetic field lines intercepted by the loop

The correct option is B

Explanation:

Generally from the  Faraday's Law of Induction voltage  is induce when there is a change in magnetic and this induced voltage will cause a difference in potential which will to an induce current , the rate at which the magnetic field change determines the magnitude of the induced current
