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

The susceptibility of a magnetic material is

- 4.2 \times 1 0^{- 6}

. Name the type of magnetic material it represents.

Answer: Diamagnetic material.

Solution

Magnetic susceptibility

χ

is negative and small (

- 4.2 \times 1 0^{- 6}

).
A small negative susceptibility means the material is weakly magnetised opposite to the applied field, which is the defining behaviour of a diamagnetic material.
