A rectangular coil lies flat on a horizontal surface. A bar magnet is held above the center of the coil with its south pole pointing down. If the magnet is dropped from this position, what is the direction of the induced current in the coil?

the direction of the flow of the induced current will be clockwise in the coil.

Explanation: according to Lenz law, an induce current acts in a direction that opposes the direction of motion (if not for this law, then we'll get a perpetual energy output with little or no energy input which destroys the law of energy conservation). As the south pole of the magnet moves towards the coil, a south pole must be induced on the coil to repel the movement of the magnet towards the coil. Clockwise flow of current produces a southpole while an anticlockwise flow produces a Northpole. This shows that the direction of the induced current will be clockwise.

a.) travels faster in solids because the particles are closer together.
