More magnets

  1. Apr 25, 2004 #1
    Can a single atom of a ferromagnetic material display properties of ferromagnetism? In other words, is an iron atom affected by magnetic fields the same way a chunk of iron is? In other other words, does a single atom of a ferromagnetic material still have a net magnetic dipole moment, or is this an emergent property of many atoms together?

    No. Ferromagnetism is a collective effect where individual atoms try to line up with their magnetic moments in the same direction.
    Yes, an iron atom is a tiny magnet, but so are other non-ferromagnetic atoms.
