A wire is bent into three circular segments, each of radius r-10 cm, each segment is quadrant of a circle, ab
lying in the xy plane, and bc lying in the yz plane and ca lying in the zx plane.
If a uniform B points in the positive x-direction,
a) what is the magnitude of the emf developed in the wire when B increases at a rate of 3.0 mT/s.
b) what is the direction of the current in segment cb?
