DESCRIPTION: A Canadian nickel has the ferromagnetic element nickel as a major part of its composition, and is strongly attracted to a magnet, as shown in the photograph. When heated above its Curie temperature by the gas torch, it loses its fe rromagnetism and falls away from the magnet to the table.
