Question: A uniform magnetic field is at right angles to the plane of a wire loop. If the field decreases by 0.20 T in 1.0 x

A uniform magnetic field is at right angles to the plane of a wire loop. If the field decreases by 0.20 T in 1.0 x 10-3s and the magnitude of the average emf induced in the loop is 80 V,
(a) What is the area of the loop?
(b) What would be the value of the average induced emf if the field change was the same but took twice as long to decrease?
(c) What would be the value of the average induced emf if the field decrease was twice as much and it also took twice as long to change?
