Among which the magnetic susceptibility does not depend on the temperature?
Text Solution
Verified by ExpertsThe correct answer is:
A
Magnetic Susceptibility and Temperature Dependency
Magnetic susceptibility ($\chi$) is a measure of how much a material will become magnetized in an applied magnetic field. It varies for different types of magnetism:
Considering the above explanations, the only type of magnetism that does not depend on temperature is diamagnetism. Therefore, the correct answer is Option A.
Magnetic susceptibility ($\chi$) is a measure of how much a material will become magnetized in an applied magnetic field. It varies for different types of magnetism:
- Diamagnetism: This is a property of all materials and is characterized by a negative susceptibility. Diamagnetic materials create an opposing magnetic field when exposed to an external magnetic field. Importantly, the magnetic susceptibility of diamagnetic materials is temperature-independent.
- Paramagnetism: Paramagnetic materials have positive susceptibility that is dependent on temperature. According to Curie's law, the susceptibility ($\chi$) is inversely proportional to the temperature (T): $\chi \propto \frac{1}{T}$.
- Ferromagnetism: Ferromagnetic materials also exhibit a strong temperature dependency. They have a specific temperature called the Curie temperature above which they lose their ferromagnetic properties.
- Ferrites: Ferrimagnetic materials, including ferrites, display temperature-dependent magnetism and will typically lose their magnetism above a certain temperature.
Considering the above explanations, the only type of magnetism that does not depend on temperature is diamagnetism. Therefore, the correct answer is Option A.
