Suppose you wanted to use Earth’s magnetic field to make an ac generator at a location where the magnitude of the field is 0.05000 mT. Your coil has 1008 turns and a radius of 3.700 cm. At what angular velocity would you have to rotate it in order to generate an emf of amplitude 1.000 V?
Homework Answers
given
magnetic field B = 0.05*10^-3 T
N = 1008 turns
radius r = 0.037 m
voltage V = 1 V
from the relation
angular velocity w = V/NBA
w = 1/1008*0.05*10^-3*3.14*0.037^2
w = 4615.7 rad/s
