A generator coil is rotated through one-fourth of a revolution (from θ = 0º to θ = 90º) in 20 ms. The 155-turn circular coil has a 6 cm radius and is in a uniform 1.78 T magnetic field which initially is pointing along the normal of the coil. What is the magnitude of the average emf (in V) induced? Enter an integer
Homework Answers
When the coil is rotated through 900, then there will be no magnetic field passing thorugh the coil.
And we know that, induced EMF is
EMF = (change in flux)/( total time taken)
EMF = (155*3.14*0.06*0.06*1.78)/20*10-3
=156V
