Question

A uniform externally applied magnetic field is in the +z direction (B = Bk, with B positive) and B is increasing with time. A loop of wire in the x-y plane is in this field (the magnetic field is perpendicular to this loop); it has a total resistance R independent of the radius r of the loop. Which of the following statements is true?

The magnitude of the current is proportional to the radius of the loop: I=αr, α a constant.
The current at any time is proportional to the magnitude of the magnetic field at that time.
The current induced in the wire will produce a magnetic field in the –z direction.
None of a-c
More than one of a-c
