Question
Draw magnetic field lines when a (i) diamagnetic, (ii) paramagnetic substance is placed in an external magnetic field. Which magnetic property distinguishes this behaviour of the field lines due to the two substances?
✓
Answer
- Diamagnetic material
- Paramagnetic material
Paramagnetic substance: permeability slightly greater than one/susceptibility small but positive.
Diamagnetic substance: permeability very slightly less than one/susceptibility very small but negative.
