The video tutorial explains how magnets can be demagnetized by heating them to a specific temperature known as the Curie temperature. It highlights that for neodymium magnets, this process can be done at home by heating them above 300°C (600°F), causing them to lose their magnetic properties.

What happens to magnets when they are heated to a high temperature?

• They become stronger.

• They lose their magnetism.

• They change color.

• They break into pieces.

What is the term used for the temperature at which magnets lose their magnetic properties?

• Curie temperature

• Melting point

• Freezing point

• Boiling point
