In which type of material the magnetic susceptibility does not depend on temperature?

Options

A. Diamagnetic
B. Paramagnetic
C. Ferromagnetic
D. Ferrite

Answer

**Step-by-Step Solution:**

1. **Understanding Magnetic Susceptibility:**
- Magnetic susceptibility (Xm) is a measure of how easily a material can be magnetized. It indicates the degree of magnetization of a material in response to an applied magnetic field.

2. **Types of Magnetic Materials:**
- There are different types of magnetic materials:
- **Diamagnetic Materials:** These materials have a very weak and negative susceptibility to magnetic fields. They do not retain magnetic properties when the external field is removed.
- **Paramagnetic Materials:** These materials have a positive susceptibility and are weakly attracted by a magnetic field. Their magnetic properties depend on temperature.
- **Ferromagnetic Materials:** These materials have a strong positive susceptibility and can retain magnetization. Their magnetic properties also depend on temperature.

3. **Effect of Temperature on Magnetic Susceptibility:**
- For paramagnetic and ferromagnetic materials, the magnetic susceptibility changes with temperature. As temperature increases, the thermal agitation disrupts the alignment of magnetic moments, leading to a decrease in susceptibility.
- In contrast, diamagnetic materials do not exhibit a change in magnetic susceptibility with temperature. Their magnetic properties remain constant regardless of temperature changes.

4. **Conclusion:**
- Therefore, the type of material in which the magnetic susceptibility does not depend on temperature is **diamagnetic material**.

**Final Answer:**
- Diamagnetic material is the type of material in which the magnetic susceptibility does not depend on temperature.
