MCQ
The magnetic materials having negative magnetic susceptibility are:
- ANon$-$magnetic.
- BPara magnetic.
- ✓Dia magnetic.
- DFerro magnetic.
✓
Answer
Correct option: C.
Dia magnetic.
Magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetisation of a material in response to an applied magnetic field.
Substances such as copper, iron have negative susceptibility as these substances are diamagnetic substances.
Substances with negative susceptibility signifies that they are repelled by magnets.
