Question:

A long, straight, current-carrying wire passes near a wire loop (Fig. P21.19). The current in the straight wire is directed to the right, and its magnitude is decreasing.
(a) What is the direction of the magnetic flux through the loop?
(b) Is the magnitude of the flux through the loop increasing or decreasing with time?
(c) What is the direction of the magnetic field produced by the induced current in the loop?
(d) What is the direction of the current induced in the loop?
(e) This induced current leads to a magnetic force on the loop. What is the direction of this force? Is it directed toward the wire or away from it?
