Question

Which transition occurs at Curie's temperature?

• A. Ferromagnetic becomes diamagnetic
• B. Paramagnetic becomes diamagnetic
• C. Ferromagnetic becomes paramagnetic
• D. Diamagnetic becomes paramagnetic

Answer 1

The correct option is C Ferromagnetic becomes paramagnetic

The temperature at which the ferromagnetic materials become paramagnetic materials is called curie's temperature. Magnetic properties of ferromagnetic material get affected when heated and hence becomes paramagnetic at curie's temperature.
