Above the curie temperature the susceptibility of a ferromagnetic substance varies
Options
- Adirectly as the absolute temperature.
- Binversely as the absolute temperature.
- Cinversely as the square root of absolute temperature.
- Ddirectly as the square root of absolute temperature.
Correct answer
B. inversely as the absolute temperature.
Step-by-step solution
1 ~T (Theory question) 15. Gain in kinetic energy = loss in potential energy aligned & 1 2 ~m (1+ k ² R ² ) V ²= mgh & 1 2 (1+ 1 2 ) V ²= gh & 3 4 ~V ²= gh & h = 3 ~V ² 4 ~g aligned
