The figure below shows a closed loop of wire that consists of a pair of equal semicircles, of radius 6.80 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 B of magnitude 95.0 mT is directed perpendicular to the fold diameter and makes equal angles (of 45.09) with the planes of the semicircles. The magnetic field is reduced to zero at a uniform rate during a time interval of 28.5 ms. 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 the loop? Magnetic field (a) Number Units V (b)A rectangular loop (area = 0.25 m2) turns in a uniform magnetic field, B = 3.0 T. When the angle between the field and the normal to the plane of the loop is it/ 2 rad and increasing at 2.9 rad/s, what emf is induced in the loop? Number 0.002175 Units mV e Textbook and Media
