When the magnet shown in the diagram below is moving towards the coil, the galvanometer gives a reading to the right.


(i) What is the name of the effect being produced by the moving magnet?


(ii) State what happens to the reading shown on the galvanometer when the magnet is moving away from the coil.


(iii) The original experiment is repeated. This time the magnet is moved towards the coil at a great speed.

(i) The name of the effect being produced by the moving magnet is electromagnetic induction.

(ii) When the magnet is moving away from the coil the needle of the galvanometer get deflected to left.


(iii) Large deflection to right occurs more quickly when the magnet is moved towards the coil at a great speed.


State two changes you would notice in the reading on the galvanometer.


two changes you would notice in the reading on the galvanometer are:-


1) it deflects toward left.


2) And it gets deflected towards right when the magnet is moved toward the coil at a great speed.
