At time t = 0, the loop moves with velocity v = 15 cm/s with its left end located a distance d = 48 cm from the y-axis. The resistance of the loop is R = 2.4 Q. What is i(0), the induced current in the loop at time t = 0? Define the current to be positive if it flows in the counter-clockwise direction. y L W 4) Suppose the loop now moves in the positive y-direction as shown.
