Step 1: Basics of magnets
1) Every magnet has two poles.The two ends of a magnet are its two poles and these are north and south.The magnetic fields of magnets are highest at its two poles, and if a magnet is broken into half or smaller or any size the ends of the new broken pieces are also the two poles. So if a magnet having two poles broken int two pieces then the newly produced magnets will have two poles each.
2)The opposite poles of two magnets attract each other.And the same poles of two magnets repel each other.
3)Magnetic force affect most of the substances,but the effect is more in some materials and less in some material.
4)Magnets attract ferromagnetic materials like iron,steel,cobalt,nickel etc.
5)If magnets are moved in between a coil of wire it produces electricity .
