Magnets have the property of attracting small pieces of iron, nickel, and cobalt due to magnetism. The earliest known magnet was a piece of the mineral magnetite, also called lodestone. Magnets have north and south poles, with opposite poles attracting and like poles repelling one another. Artificial magnets can be created by making pieces of iron acquire magnetic properties, and magnets exert influence within their magnetic field.

3. The substances which have the property of
attracting small pieces of Fe,Co,Ni etc are
called magnets, and this property of attraction
is called magnetism.

4. It is a piece of Iodestone,which is a black iron
oxide called magnetite. The word Iodestone
means a leading stone.

6. The regions of concentrated magetic strength
inside the magnet just near its ends are called
magnetic poles.The pole of a freely suspended
magnet which points towards north is called
north pole and that point towards south is called
south pole.

8. It states that like poles repel while unlike poles of
magnets attract each other.

10. 1. Magnets attract small pieces of Fe,Ni,Co etc.
2. When freely suspended, they come to rest in
north south direction.
3. Like magnetic poles repel each other and unlike
magnetic poles attract each other.
4. The magnetic poles always exist in pairs.

11. Pieces of Fe and other magnetic materials which
can be made to acquire the properties of
natural magnets are called artificial magnets.

12. It is a region around the magnet with in which its
influence can be experienced.
