Paramagnetism and Curie’s law
Cool a paramagnet and watch its atomic dipoles line up with the applied field more easily.
What to notice
Thermal agitation fights alignment, so susceptibility rises as temperature falls.
Key relation
χ = C / T ; M = χH
Try this
Halve the absolute temperature. What happens to the magnetisation?
What you can change
- Temperature: 4 to 400 K
- Curie constant C: 0.01 to 1 K
- Applied field H: 1 to 100 kA/m
