Question

A magnet falls through a loop of wire with the south pole entering first. As the south pole approaches the loop, what is the direction of the induced current in the loop {as viewed from above, looking down on the magnet)? Explain why it is in this direction using Lenz's Law. A magnet falls through a loop of wire with the south pole entering first. After it has fallen all the way through, so that the north pole end is moving away from the loop, what is the direction of the induced current in the loop (as viewed from above, looking down on the magnet)? Explain using Lenz's Law.

Explanation / Answer

lenz's law states that the direction of induced current is such that it always opposes the rate of change of magnetic flux through the loop

So from the South pole the field lines go away from the loop,so to increase the flux through the loop the direction of current must be in Clockwise direction

coming to Question 2) when the north pole was leaving the loop,the direction of current must be in counterclockwsie direction in the loop
