The magnetic susceptibility is negative for:

Question

Accepted Answer

1. **Definition:** Magnetic susceptibility ($\chi$) is a measure of how a magnetic material responds to an external magnetic field.
2. **Diamagnetic Materials:** For diamagnetic substances, the material is feebly repelled by the magnetic field. This corresponds to a **negative** magnetic susceptibility, typically in the range $-1 \le \chi < 0$ .
3. **Paramagnetic Materials:** These substances are weakly attracted by a magnetic field, corresponding to a small **positive** susceptibility ($0 < \chi < \epsilon$) .
4. **Ferromagnetic Materials:** These substances are strongly attracted by a magnetic field, corresponding to a large **positive** susceptibility ($\chi \gg 1$) .
5. **Conclusion:** Only diamagnetic materials exhibit negative magnetic susceptibility.
