magnetism
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.
It is a piece of Iodestone,which is a black iron 
oxide called magnetite. The word Iodestone 
means a leading stone.
magnetism
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.
magnetism
It states that like poles repel while unlike poles of 
magnets attract each other.
magnetism
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.
Pieces of Fe and other magnetic materials which 
can be made to acquire the properties of 
natural magnets are called artificial magnets.
It is a region around the magnet with in which its 
influence can be experienced.
THANK YOU
