Question
Suppose the number of turns in a rectangular coil of wire that is rotating in a magnetic field is tripled, what happens to the induced emf, assuming all the other variables remain the same?
It is reduced by a factor of 3
It is reduced by a factor of 9
It is increased by a factor of 3
It it reduced by a factor of 9
It remains the same
Suppose the rate of change of the magnetic field applied to a loop of wire is tripled, what happens to the induced emf in the loop assuming all of the other parameters remain unchanged?
It is reduced by a factor of 3
It is reduced by a factor of 9
It is increased by a factor of 3
It it reduced by a factor of 9
It remains the same
Explanation / Answer
e = N.A.B Cos (theta) / dt
e directly proportional to N
So e :- It is increased by a factor of 3
e also fdirectly proportional to dB/dt
so e :- It is increased by a factor of 3
