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
Answer:
The correct option is B
Step-by-step 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
