Question
The susceptibility of a magnetic material is − 2.6 × 10−5. Identify the type of magnetic material and state its two properties.
Solution
Diamagnetic materials have negative susceptibility. So the given magnetic material is diamagnetic.
Two properties of diamagnetic material:
(1) They do not obey Curie’s law.
(2) They are feebly repelled by a magnet.
