A paramagnetic substance in the form of a cube with sides 1 cm has a magnetic dipole moment of

20 \times {10^{ - 6}}J\mathrm{/}T

when a magnetic intensity of

60 \times {10^3}A\mathrm{/}m

is applied. Its magnetic susceptibility is

View answer and explanation

Correct option: A

3.3 \times {10^{ - 4}}

Option A (

3.3 \times {10^{ - 4}}

) is correct because it is the magnetic susceptibility calculated using the given magnetic dipole moment and magnetic intensity.
