(But you're in luck, because I've already drawn it out before if you want to see.). If the substance is placed in a magnetic field, the direction of its induced magnetism will be opposite to that of iron (a ferromagnetic material), producing a repulsive force. I'm looking for a piece of glassware from France? Unlike ferromagnetism, paramagnetism does not persist once the external magnetic field is removed because thermal motion randomizes the electron spin orientations.
