K1 falling K1: The metal loop shown is falling towards the bar magnet indicated

Question

K1 falling K1: The metal loop shown is falling towards the bar magnet indicated and will pass between the poles. As the loop approaches the magnet from above as shown, will the direction of induced current that we see in the loop be clockwise or counterclockwise from our diagram view? Show your steps in the determination. Getting closer, but magnet in question K1 K2 K2: Given the magnet moving away from the coil in the diagram shown, determine the direction of the induced current through the ammeter shown. Does the current go through the ammeter from left to right, or from right to left? Show your work and steps. N S Coil Moving

Explanation / Answer

1. As magnetic Field of magnet is from north to south, the induced current should produce its own magnetic field opposite, therefore induced current should be anticlockwise.

2. Since North of magnet is moving away, the induced current should produce its magnetism in such a way, that it should have its south Pole near to the North Pole of magnet. Therefore Current should be from left to right through the Ammeter.
