Question

The armature of a simple ac generator has 20 circular loops of wire, each with a radius of 10cm . It is rotated with a frequency of 60Hz in a uniform magnetic field of 500mT .


What is the maximum emf induced in the loops?
Express your answer using two significant figures.
eo= ? V




Part B
How often is this value attained?
Express your answer using two significant figures.
T= ? s




Part C
If the time period in part B were cut in half, what would be the new maximum emf value?
Express your answer using two significant figures.
eo=? V



Please help how would I approach this. Thank you!

Explanation / Answer

solved a similar question already with different numbers.. i put the question and the answer.. hope it helps!! :) kindly rate a life saver :)

The armature of a simple ac generator has 20 circular loops of wire, each with a radius of 10 cm. It is rotated with a frequency of 60 Hz in a uniform magnetic field of 900 mT.

What is the maximum emf induced in the loops?
E0=....V

How often is this value attained?
T=.....s

If the time period in part B were cut in half, what would be the new maximum emf value?
E0=...V
