why magnets attract things.ans deeply
Answers
Magnets doesn't attract all things they only attracts metals.
It depends on the permeability of the material. Permeability is the measure of the ability of a material to support the formation of a magnetic field within itself.
So the magnet attracts everything(even you) but the strength of attraction depends on the permeability of the material. If a material is strongly attracted to the magnet then it is said to have a high permeability.
The permeability for Iron is 0.25 henries/meter(H/m)

Magnetism is based on electron spins. There are two electron spin directions clockwise and anti clockwise. If you look at the electronic configuration some are fully filled electron blocks and some are partially filled electron blocks. Fully filled has both spins and gets cancelled causing with no net spin and no magnetism. Partially filled has only one spin direction with net spin causing magnetism. This occurs for monovalent atoms. For divalent atoms, even though they have partially filled blocks and has a net spin as a single atom, they get cancelled when they pair to form divalent atom.
Compare electronic configuration of Iron vs Gold and Silver. Gold and Silver have all electron blocks fully filled except one block. Iron has more partially filled electron blocks
