In Diamagnetic materials-a)Susceptibility is independent of temperatur...
Magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field.
The magnetic susceptibility decreases with an increase in temperature. So, the ferromagnetism decreases with rising temperature. It is maximum at absolute zero temperature and becomes zero at Curie temperature. Above this temperature, the ferromagnetic material behaves as paramagnetic substance.
In diamagnetic materials, susceptibility is independent of temperature.

Diamagnetic Materials Overview
Diamagnetic materials are a class of materials that exhibit a weak form of magnetism. When an external magnetic field is applied, these materials create an induced magnetic field in the opposite direction, leading to a repulsive effect.
Understanding Magnetic Susceptibility
- Magnetic Susceptibility (χ): This is a measure of how much a material will become magnetized in response to an external magnetic field. For diamagnetic materials, the susceptibility is negative and very small.
Temperature Independence
- Constant Susceptibility: In diamagnetic materials, the magnetic susceptibility is generally considered independent of temperature. This means that regardless of the temperature change, the susceptibility remains relatively constant.
- Reasons for Independence:
- Electron Configuration: The magnetic behavior arises from the pairing of electrons in their atomic orbitals. Since paired electrons create a net zero magnetic moment, this pairing does not change with temperature.
- Weak Response: The response of diamagnetic materials to an external magnetic field is very weak and does not depend on thermal agitation, unlike paramagnetic or ferromagnetic materials where susceptibility changes with temperature.
Comparison with Other Materials
- Paramagnetic Materials: In contrast, these materials show an increase in susceptibility with temperature due to unpaired electrons aligning with the external magnetic field.
- Ferromagnetic Materials: Their susceptibility can also change significantly with temperature, often reaching a Curie point where they lose their magnetic properties.
Conclusion
In summary, the correct answer is option 'A' because diamagnetic materials maintain a constant susceptibility that does not vary with temperature, distinguishing them from other magnetic materials.
