The correct answer is option D - all of above.
The principle of the present day magnetic compass is the same as that of the compasses used by ancient mariners.
The magnetic compass consists of a magnetized needle, or an array of needles, allowed to rotate in the horizontal plane. Any magnetized piece of metal will have regions of concentrated magnetism called poles. Any such magnet will have at least two poles of opposite polarity. Magnetic force (flux) lines connect one pole of such a magnet with the other pole. The resting poles of the needle in the compass are the North-South direction.

The correct option is D
Explanation:
1. Magnet is an object which attracts metals like Iron, cobalt , Nickel and steel.
2. Magnetic field is stronger at poles.
3 A magnet has two poles North and South poles
4 like poles repel each other and unlike poles attract each other.
5. When magnet is suspended freely it aligns itself in North and South direction.
Hence all of the above.
