Which of the following magnetic materials' properties is temperature dependent?
Correct answer: D. Both B and C
- A. Diamagnetism
- B. Paramagnetism
- C. Ferromagnetism
- D. Both B and C
Explanation
Both paramagnetism and ferromagnetism are temperature-dependent. Paramagnetic susceptibility is inversely proportional to temperature (Curie's Law). Ferromagnetism disappears above the Curie temperature, where the material becomes paramagnetic. Diamagnetism is largely independent of temperature.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
