A circular coil has 350 turns and a radius of 5.50 cm. The coil is used as an ac generator by rotating it in a 0.750 T magnetic field. Through how many revolutions will the coil rotate in one minute if the maximum emf is 169 V? Answer in revs
Homework Answers
Here,
let the angular speed is w
Now, for the peak emf
peak emf = Area * N * w * B
169 = pi * 0.055^2 * 350 * w * 0.750
solving for w
w = 67.7 rad/s = 646.6 rpm
the angular speed is 646.6 rpm
