Front

How can permanent magnets be demagnetized?

Back

What is the Curie point?

Back

The Curie point is the temperature at which a material loses its permanent magnetic properties.

Front

What is the difference between a permanent magnet and a temporary magnet?

Back

A permanent magnet retains its magnetism over time, while a temporary magnet only exhibits magnetic properties when in a magnetic field.
