CBSE Class 12 · 2011 · Magnetic Properties of MatterVery Short Answer

The susceptibility of a magnetic material is

1.9 \times 1 0^{- 5}

. Name the type of magnetic material it represents.

Answer: Paramagnetic material.

Solution

Magnetic susceptibility

χ

is positive and small (

+ 1.9 \times 1 0^{- 5}

).
A small positive susceptibility means the material is weakly magnetised along the applied field, which is the defining behaviour of a paramagnetic material.
