When a magnetic field is applied to a diamagnetic, the dipoles align opposite to the direction of the magnetic field. However, when a magnetic field is applied to a paramagnetic, the dipoles align to the same direction of the magnetic field. My professor mentioned in class that the phenomenon of diamagnetic and paramagnetic dipole alignment is unexplained and challenged us to find some sort of factual backing for our explanation. I am asking for help, for guidance, for any ideas on this phenomenon. Any suggestions?
