The geographical direction in which the magnets align themselves when suspended in air is ___ .
North-South
Magnets align in the North-South direction when suspended in the air as the magnetic poles of the Earth (which is the strongest magnet around them) are in the North-South direction. The magnetic south pole of Earth is also its geographical north pole and vice-versa. The north pole of the suspended magnet gets attracted to the magnetic south pole of Earth (geographical north pole) and vice versa. This is the reason why an isolated suspended magnet always aligns itself in North-South direction.
