Description: A ball of iron is attached to a magnet. Heat the iron near the magnet and it should fall after a few seconds.
Note: Be careful not to heat up the magnet or catch the wood on fire.
Explanation: A ball of iron ordinarily will be attracted to a magnet, but when you heat the
ball to a temperature of at least 176° Fahrenheit (called the Curie point), it loses its ability to be
magnetized. Heat energy scrambles the iron atoms so they can’t line up and create a magnetic
field, thus why the ball falls off of the magnet.
