Magnets were the ‘magical stones’ we loved when we were young.  They produce a magnetic field which is invisible which somehow attracted other magnets or magnetic materials.  But, how do magnets actually work?  

Firstly, a magnet is made up on a North-seeking pole and a South-seeking pole, with points in the direction of North and South respectively.  Properties of magnets include its ability to attract other magnetic materials, and they also have 2 poles where the resultant attractive force appears to be concentrated.  Additionally, when freely suspended, magnets come to rest with the North Pole pointing in the North and South Pole pointing in the South.  Also, like poles repel and unlike poles attract.

Secondly, induced magnetism is the phenomenon whereby a magnetic substance is magnetized by a magnetic field.  Thus when magnetized, it always results in 2 poles and leads to attraction.  Thus it is very important as the theory of magnetism is needed to understand how magnets work.

In magnetic substances, atoms behave like tiny atomic magnets.  With a group of atomic magnets pointing in the same direction, ...
