(a) The diagram shown a bar magnet surrounded by four plotting compasses. Copy the diagram and mark in it the direction of the compass needle for each of the cases B, C and D.
(b) Which is the north pole, X or Y?
(a)
(b) X is the North pole.
How does a compass work? Is its needle only a magnet or even the north pole marked on the compass is a magnet ?
Why does a compass needle get deflected when placed in a magnetic field? is it because the north pole of the compass needle and north pole of the magnet deflect?
If a compass is kept exactly between the north poles of 2 similar bar magnets, then in which direction will its needle get deflected to?
