AP EAMCET · PHYSICS · Magnetic Properties of Matter
A paramagnetic sample showing a net magnetization of , when placed in an external magnetic field of strength , at a temperature . If the temperature is raised to , then the magnetization becomes
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Using Curie's law, M=CBT here M is the magnetization, B is the magnetic field, T is the absolute temperature and C is Curie's constant. Now, given that M1=0.8 A m-1 if B1=0.8 T and T1=5 K therefore,…
