you hold a wire coil so that the plane of the coil is perpendicular to a magnetic field b⃗ .
A circular loop of wire lies flat on a level tabletop. A bar magnet is held stationary above the circular loop with its north pole point downward. As viewed from above, in what direction does the induced current flow in the loop of wire?
1. No current is induced in the loop of wire.
2. An induced current flows clockwise in the loop of wire.
3. An induced current flows counterclockwise in the loop of wire.
4. The direction of the induced current cannot be determined from the given information.
