MCQ
Liquid oxygen remains suspended between two pole faces of a magnet because it is
  • A
    Diamagnetic
  • ✓
    Paramagnetic
  • C
    Ferromagnetic
  • D
    Antiferromagnetic
✓

Answer

Correct option: B.
Paramagnetic
b
(b) Oxygen is paramagnetic in nature. So if it will be attracted both by North pole or South pole. When it is placed exactly between two magnetic poles, the forces acting on it due to magnetic poles will be ailequal $\&$ opposite. Hence it will remain suspended between them.
