What happens to the magnetic susceptibility of a paramagnetic material when its absolute temperature is increased?
A. It increases linearly
B. It decreases inversely✓ Correct Answer
C. It remains completely constant
D. It drops immediately to zero
💡 Solution & Explanation
Curie's law states that the magnetic susceptibility of a paramagnetic material is inversely proportional to its absolute temperature, meaning that thermal agitation disrupts alignment with an external magnetic field as temperature rises. When absolute temperature increases, the atomic magnetic dipoles are randomized more effectively, causing susceptibility to decrease. Ferromagnetic materials follow a different relationship known as the Curie-Weiss law at high temperatures. Physics concepts regarding magnetic properties are frequently tested in general science papers.
