A wire is bent into three circular segments, each of radius r = l0 cm, as shown in Figure. Each segment is a quadrant of a circle, ab lying in the xy plane, b c lying in the y z plane, and ca lying in the z x plane.

(a) If a uniform magnetic field B points in the positive x direction, what is the magnitude x of the emf developed in the wire when B increases at the rate of 3.0mTA?

(b) What is the direction of the current in segment bc?
