Question

How mognet lose magnetism​

Answer 1

Answer:

As the temperature increases, at a certain point called the Curie temperature, a magnet  will lose its strength completely. Not only will a material lose its magnetism, it will no longer be attracted to to magnets. Once the metal cools, its ability to attract magnets  returns, though its permanent magnetism  becomes weak.

Answer 2

Answer:

Magnetic materials lose magnetism as they heat, but they regain magnetism when cooled provided the maximum temperature is below their Curie temperature. hope this helps :)
