Q. A rectangular conductor
LMNO is placed in a uniform magnetic field of
0.5 T. The field is directed perpendicular to the plane of the conductor. When the arm
MN of length of
20 cm is moved towards left with a velocity of
10ms−1 calculate the emf induced in the arm. Given the resistance of the arm to be
5Ω (assuming that other arms are of negligible resistance) find the value of the current in the arm.
