COMEDK · Physics · 20. Magnetic Properties of Matter
Curie-Weiss law is obeyed by iron
- A at Curie temperature only
- B at all temperatures
- C below Curie temperature
- D above Curie temperature
Answer & Solution
Correct Answer
(D) above Curie temperature
Step-by-step Solution
Detailed explanation
Ferromagnetic materials like iron obeys Curie-Weiss law above its Curie temperature. According to Curie-Weiss law, magnetic susceptiblity \((\chi)\) of ferromagnetic material is related with temperature \(T\) as \[ \chi=\frac{C}{T-T_{C}} \] where, \(C=\) Curie constant and…
