A long, vertical, straight wire carries a current I in Figure 1.8. The wire is perpendicular to the plane of a circular metal loop and passes through the center of the loop (see the drawing). The loop is allowed to fall and maintains its orientation with respect to the straight wire while doing so. In what direction does the current induced in the loop flow?

A long, vertical, straight wire carries a current I. The wire is perpendicular to the plane of a circular metal loop and passes through the center of the loop (see the drawing). The loop is allowed to fall and maintains its orientation with respect to the straight wire while doing so. In what direction does the current induced in the loop flow? (A) There is no induced current. (B) It is flowing around the loop from A to B to C to A (C) It is flowing around the loop from C to B to A to C Open Ended: I. A coil of wire consists of 20 turns each of which has an area of 0.0015 m'. A magnetic field is perpendicular to the surface. Initially, the magnitude of the magnetic field is 0.050 T and 0.10s later, it has increased to 0.060 T.
