Question

The magnetic properties of magnets are

• A. Lost at its boiling point
• B. Gained at its melting point
• C. Intake at Triple point
• D. Lost at its Curie point

Hint:

Remember, the Curie point is crucial when studying ferromagnetic materials. It's the temperature at which the material stops being magnetically aligned.

Answer 1

The Correct Option is D

The magnetic properties of a material are lost when it reaches its Curie point. The Curie point, also known as the Curie temperature, is the temperature at which certain materials lose their permanent magnetic properties and become paramagnetic. Above this temperature, the thermal energy is sufficient to overcome the magnetic alignment of atoms, thus the material no longer exhibits ferromagnetism.
