1.	When a compass needle be placed at magnetic north pole, how would it behave? If a dip needle be placed at the place, how would it behave?
Answer» Compass needle stays in horizontal north-south direction. At poles horizontal component H= 0; therefore there will be no effect of earth’s field on magnetic north pole and it can stay in any direction; on the other hand a dip needle points along the resultant magnetic field and at poles the resultant field is vertical; hence the needle becomes vertical.
