A straight wire lies along the y-axis. It is initially carrying a current of 10 A in the positive y-direction. This current decreases to zero, then reverses to flow at 10 A in the negative y-direction. 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. As the current in the straight wire is in the process of changing, in which direction is the induced current flow, along the side of the square coil nearest to the straight wire?

a.

At first it is in the positive y-direction, but after the current passes through zero, it is in the negative y-direction.
b.

At first it is in the negative y-direction but after the current passes through zero, it is in the positive y-direction.
c.

It is in the negative y-direction.
d.

It is in the positive y-direction.
