A straight wire lies along the y-axis initially carrying a current of 10 A in the positive y-direction. The current decreases and reverses to 10 A in the negative y-direction, the change in current happening at a uniform rate. In the 1st quadrant a square conducting coil has 2 sides parallel to the y-axis and the other 2 sides parallel to the x-axis. The side of the coil nearest and parallel to
the straight wire is at a distance equal to the length of one of the sides of the square. As the current is going from 10 A in one direction to 10 A in the other, in which direction is the induced current in this side of the square coil nearest to the straight wire? a. It is in the positive y-direction. b. It is in the negative y-direction. c. At first it is in the positive y-direction, but after the current passes through zero, it is in the negative y-direction. d. At first it is in the negative y-direction but after the current passes through zero, it is in the positive y-direction.
