Susceptibility of a paramagnetic substance is (a) negative and large. (b) negative and small. (c) positive and large. (d) positive and small.

Answer: (d). Paramagnetic dipoles align weakly along the field, so χ is positive but small (about 10⁻⁵ to 10⁻³). So the answer is (d) positive and small.

Susceptibility of a paramagnetic substance is

Show answer and solution

Answer: (d)

Paramagnetic dipoles align weakly along the field, so $\chi$ is positive but small (about $10^{-5}$ to $10^{-3}$ ).
So the answer is (d) positive and small.
