MCQ
Curie temperature is the temperature above which
  • A
    A paramagnetic material becomes ferromagnetic
  • A ferromagnetic material becomes paramagnetic
  • C
    A paramagnetic material becomes diamagnetic
  • D
    A ferromagnetic material becomes diamagnetic

Answer

Correct option: B.
A ferromagnetic material becomes paramagnetic
b
(b) At Curie temperature, there is a change from ferromagnetic to paramagnetic behaviour. Above this temperature, the paramagentic substance obeys Curie Weiss law, even those resistances which are not ferromagnetic but only paramagnetic also obey Curie Weiss law above the Curie temperature only.
