Question:
Figure shows a closed loop of wire that consists of a pair of equal semicircles, of radius 3.7 cm, lying in mutually perpendicular planes. The loop was formed by folding a flat circular loop along a diameter until the two halves became perpendicular to each other. A uniform magnetic field E of magnitude 76mT is directed perpendicular to the fold diameter and makes equal angles (of 45?) with the planes of the semicircles. The magnetic field is reduced to zero at a uniform rate during a time interval of 4.5ms. During this interval, what are the
(a) Magnitude and
(b) Direction (clockwise or counterclockwise when viewed along the direction of B) of the emf induced in theloop?
