Magnetic Susceptibility

Diamagnetic materials have susceptibility that is:
Select the correct option:
Solution
Incorrect! Answer:
Negative
Magnetic Susceptibility (χ) represents how easily a material becomes magnetized.
- For Diamagnetic materials, an induced magnetic field opposes the external field (Lenz's Law effect in atomic orbits).
- Therefore, χ is negative (and very small, e.g., ∼−10−5).
- These materials are independent of temperature (except some superconductors).
