A sliding rod AB of resistance R is shown in the figure. Here magnetic field B is constant and is out of the paper. Parallel wires have no resistance and the rod is moving with constant velocity v. The current in the sliding rod AB when switch S is closed at time t=0 is

A conducting circular loop of radius a and resistance per unit length R is moving with a constant velocity v_0 , parallel to an infinite conducting wire carrying current i_0 . A conducting rod of length 2a is approaching the centre of the loop with a constant velocity v_0/2 along the direction 2 of the current. At the instant t = 0 , the rod comes in contact with the loop at A and starts sliding on the loop with the constant velocity. Neglecting the resistance of the rod and the self-inductance of the circuit, find the following when the rod slides on the loop. (a) The current through the rod when it is at a distance of (a/2) from the point A of the loop. (b) Force required to maintain the velocity of the rod at that instant.
