Q140 / 180 · AIIMS 2004 · Physics

Liquid oxygen remains suspended between two pole faces of a magnet because it is

A
diamagnetic
Correct answer
B
paramagnetic
C
ferromagnetic
D
antiferromagnetic.

Solution

Molecular bonding of $\mathrm{O}_2$ based on orbitals show that $\mathrm{O}_2$ is paramagnetic, which is true experimentally.

Hence, the correct answer is option: 'B'.
