The catenation property of carbon atoms with their valency as 4 make them available in all organic substances. Similarly, the ferrous form of iron is favoured by the "gravity" of atoms of a magnet. The atoms present in a magnet does not make the characteristic of attracting a magnetic substance but the physical speciality of "ferrous" iron makes it favoured by the atoms of a magnet. Any magnet can be created from a conducting material thro' electromagnetism. Therefore, it is not a need to be a specific atom but a magnetic substance like ferrous but not ferric iron atoms.

a piece of metal has many small, microscopic, magnetic fields, but they are all arranged in random alignment and cancel each other out. when brought near a magnet, the direction of all the fields in magnet align in the same direction of the magnet. i believe that what causes natural magnets is still unknown
