In the textbook you saw that a simple model of an atom with a single unpaired electron predicts a magnetic dipole moment of approximately 1e-23 a · m2 for one atom. if we assume that in your bar magnet all the atoms are aligned, what would you predict from this simple model for the magnetic dipole moment of your bar magnet? the primary constituent of the magnet is iron. is there rough agreement between your experimental value and this theoretical prediction? explain what a reasonable criterion for "good agreement" with the model prediction should be.
