A square shaped, conducting wire loop of side L , total mass m and total resistance R initially lies in the horizontal x-y plane, with corners at (x, y, z) = (0,0,0), (0, L , 0), (L, 0 ,0), and (L, L, 0) . There is a uniform upward magnetic field in the space within and around the loop. The side of the loop that extends from (0, 0, 0)to (L, 0, 0) is held in place on the x-axis, the rest of the loop is released, it begins to rotate due to the gravitational torque.

(d) Is mechanical energy conserved as the loop rotates downward ? Explain.

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.

Consider a variation of the previous problem. Suppose the circular loop lies in a vertical plane. The rod has a mass m. The rod and the loop have negligible resistance but the wire connecting O and C has a resistance R. The rod is made to rotate with a uniform angular velocity (omega) in the clockwise direction by applying a force at the midpoint of OA in a direction perpendicular to it. Find the magnitude of this force when the rod makes an angle (theta) with the vertical.
