Consider the following pairs regarding magnetic substances.  I. Ferromagnetic Substance: Nickel  II. Diamagnetic Substance: Silver  III. Paramagnetic Substance: Sodium  Which among the above is/are NOT correctly matched? Correct Answer All I, II and III are correct 

  • Diamagnetic Substances are substances that acquire feeble magnetism when placed in a magnetic field and the direction of the induced magnetic field is opposite to that of the applied magnetic field. Examples are bismuth, copper, silver, gold, mercury etc. 
  • Paramagnetic Substances are substances that acquire feeble magnetism when placed in a magnetic field and the direction of the induced magnetic field is the same as that of the applied magnetic field. Examples are aluminium, manganese, platinum etc. 
  • Ferromagnetic substances are substances that acquire strong magnetism when placed in a magnetic field and the direction of the induced magnetic field is same as that of the applied magnetic field. Examples are iron, cobalt, nickel etc.
