Above the Curie temperature, a ferromagnetic material:
ABecomes a perfect diamagnetic, repelling fields strongly
BMagnetises permanently and never loses the field again
CStays ferromagnetic but with a much larger susceptibility
DLoses its ferromagnetism and behaves as paramagnetic
Answer & Solution
Correct answer: D. Loses its ferromagnetism and behaves as paramagnetic
Above the Curie temperature the aligned domains thermalise and the material is paramagnetic.
