Practice question · True or false
The relative permeability of a diamagnetic material is slightly less than 1.
Hints
- What is the sign of the diamagnetic susceptibility?
- Diamagnets oppose the applied field, so their susceptibility is negative.
Show the answer
True
Why
True, diamagnets have , giving just below 1. This is where the magnetic case departs from the dielectric one, where is always above 1.
