(B) A metal loses magnetic properties.
(C) A metal loses conductivity
(D) Transmutation of metal occurs
Correct Answer : A metal loses magnetic properties.
Question Asked : SSC Combined Graduate Level Tier-I Exam 2010
Explanation : The Curie temperature (Tc), or Curie point, is the temperature at which a ferromagnetic material becomes paramagnetic on heating; the effect is reversible. A magnet will lose its magnetism if heated above the Curie temperature. The paramagnetic are feebly magnetic in nature than ferromagnetic materials such as iron, cobalt and nickel.
