A circular loop (10 turns) with a radius of 29 cm is in a magnetic field that
oscillates uniformly between 0.95 T and 0.45 T with a period of 1.00 s.
a. How much time is required for the field to change from 0.95 T to 0.45 T?
b. What is the cross-sectional area of one turn of the loop?
c. Assuming that the loop is perpendicular to the magnetic field, what is the
induced emf in the loop?
