4. Identical single loops A and B are oriented so they initially have the maximum amount of flux in a magnetic field. Loop A is then quickly rotated so that its normal is perpendicular to the magnetic field, and in the same time, B is rotated so its normal makes an angle of 45° with the field. How do their induced emfs compare:

(a) they are the same;

(b) A’s is larger than B’s;

(c) B’s is larger than A’s; or

(d) you can’t tell the relative emf magnitudes from the data given?
