Physics · Magnetism and Matter
A paramagnetic sample shows a net magnetisation of 8 Am−1 when placed in an external magnetic field of 0.6 T at a temperature of 4 K. When the same sample is placed in an external magnetic field of 0.2 T at a temperature of 16 K, the magnetisation will be:
- 1323 Am−1
- 223 Am−1✓
- 36 Am−1
- 42.4 Am−1
Correct answer
23 Am−1
