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

Answer:

There will be no induced current

Explanation:

This question requires us to tell the direction which the current induced in the loop flows.

As current changes in a conductor, so also would the magnetic field that is produced by this conductor. The magnetic field lines are parallel to rings plane.

So no current is induced I the ring. Since the wire has zero current, the magnetic field would stay the same The flux which is associated with this ring is going to remain as zero and there would be no induced current.
