At the Curie temperature, the ferromagnetic materials get converted into

  • A.Diamagnetic materials
  • B.Non-magnetic materials
  • C.Paramagnetic materials
  • D.None of the others

Answer: C

Above the Curie temperature a ferromagnet becomes paramagnetic.

Thermal agitation destroys the alignment of the magnetic domains, so the spontaneous magnetisation vanishes, though the atoms keep their individual moments and still respond weakly to an applied field. Iron's Curie point is 770 °C.
