Mention the word magnetism and most of us think of one iron-based object attracting another.  This form of magnetism is called ferromagnetism.  Iron, nickel and cobalt are the most common elements that exhibit ferromagnetic properties.  However, two other less familiar forms of magnetism also exist.  These are called paramagnetism and diamagnetism.  This video shows an example of diamagnetic of an unlikely object – a tomato.

The following video provides a useful summary of how the three forms of magnetism differ.
