Three small metal rods, one of bismuth, one of aluminum and one of iron, are attached via extremely thin filaments to hooks, so that you can suspend them between the pole pieces of an electromagnet. When you do this and then turn the magnet on, the bismuth rod (diamagnetic) orients itself at right angles to the magnetic field (below left), the aluminum rod (paramagnetic) aligns itself with the magnetic field (below center), and the iron rod (ferromagnetic) is strongly attracted to either of the pole pieces (below right).
