MG.4(1) – Magnetic Property of Iron
A piece of iron is heated by holding it over a Bunsen burner flame. At the Curie temperature, a magnet no longer attracts it. Remove the flame from underneath it. As it cools down, the piece of iron will regain its attraction to the magnet.
MG.4(2) – Curie Temperature Demo
When the magnet is heated to its Curie temperature (using a propane torch), the paper clip is attracted to it.
