Curie temperature

• D+35+20

A loop of Nickel Wire is attached to a heavy object by a light string. It is held in mid-air trough attraction to a strong magnet. If the loop is heated with flame from a lighter the internal temperature of the nickel will surpass the Curie temperature of Nickel and the loop will suddenly drop to the ground.
