Suppose there is a double loop of wire (making 2 turns) is in the x-y plane centered at the origin. There is also uniform magnetic field is increasing at a constant rate in the positive z-direction.Viewed from the positive z-axis, in which direction is the induced magnetic field in the loop?

1. Consider Lenz's law: the current induced will generate a magnetic field that opposes the +z axis. My right hand then tells me it will generate a current that is clockwise.

2. so the induced magnetic field in the loop will be in the negative z direction?
