An infinite straight wire carries current I, = 4 A in the positive y- direction as shown. At time t = 0, a conducting wire, aligned with the y- direction is located a distance d = 55 cm from the y-axis and moves with velocity v = 12 cm/'s in the negaitve x-direction as shown. The wire has length W = 26 cm. I1 W d 1) What is s(0), the emf induced in the moving wire at t = 0? Define the emf to be positive if the potential at point a is higher than that at point b. 4.538e-8 Submit You currently have 1 submissions for this question. Only 6 submission are allowed.

At time t = 0, the loop moves with velocity v = 12 cm/s with its left end located a distance d = 55 om from the y-axis. The resistance of the loop is R = 1.1 0. 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.
