jerryyu Posted August 15, 2010 Share Posted August 15, 2010 i thought that if the individual electrons in a current had its own magnetic moment, shouldn't negatively charged particles be also possess that property ? Link to comment Share on other sites More sharing options...
swansont Posted August 15, 2010 Share Posted August 15, 2010 Yes, they do, and they will align in the presence of an external field. In order for them to create a net field, you would have to spin-polarize them so that all of the individual fields add up — if they are randomly aligned, the fields will cancel. This is the difference between ferromagnetic and non-ferromagnetic materials: you have unpaired electrons that can be aligned and because the atoms are in a lattice structure they can keep this alignment.
