Class 12 Chemistry The Solid State Paramagnetism

Paramagnetism

  • Paramagnetic substances are weakly attracted on application of magnetic field.
  • It is due to presence of one or more unpaired electrons that gets attracted by the magnetic field.
  • Application of a magnetic field magnetizes the paramagnetic substances in the same direction.
  • They lose their magnetism in the absence of magnetic field.
  • O2, Cu2+, Fe3+, Cr3+ are some examples of such substances.
