A compass needle which is allowed to move in a horizontal plane is taken to a geomagnetic pole It:
Options
(a) will become rigid showing no movement
(b) will stay in any position
(c) will stay in north-south direction only
(d) will stay in east-west direction only
Correct Answer:
will stay in any position
Explanation:
Since magnetic field is in vertical direction and needle is free to rotate in horizontal plane only so magnetic force cannot rotate the needle in horizontal plane so needle can stay in any position.
