Magnets and Magnetism

Yes, the forces of attraction in a magnet are maximum at both north pole and south pole as the magnetic lines of force start from the north pole and end at the south pole.

Yes, it is the correct answer. A freely suspended magnet always comes to rest in the north-south direction. Earth is a giant magnet and its magnetic south pole is towards the geographic north pole. As opposite poles of two magnets attract each other, therefore the north pole of the bar magnet  points in the direction of the geographic north pole (magnetic south pole of the earth) and south pole of the bar magnet towards the geographic south pole of the earth (magnetic north pole of the earth).

It is the correct answer. Magnets lose their property when hammered, heated or dropped from some height, so they should be handled properly.

It is the correct answer. According to laws of magnetism, unlike poles of two magnets attract each other whereas like poles repel one another.

It is the correct answer. Magnetite, also called lodestone, is a natural magnet.
