| \(M\) = Magnetization of the Material | \(A\;/\;ft\) | \(A\;/\;m\) |
| \(C\) = Curie Constant (Material Specific Property) | - | \(A/mk\;/\;T\) |
| \(B\) = Applied Magnetic Field | \(G\) | \(T\) |
| \(T\) = Absolute Temperature | \(F\) | \(K\) |
Curie's law describes the magnetic behavior of paramagnetic materials like platinum or aluminum. It states that the magnetization of a paramagnetic material is directly proportional to the applied magnetic field but inversely proportional to the material's absolute temperature. Other words, as a paramagnetic material heats up, its magnetic properties weaken because the increased thermal energy causes the magnetic moments of its atoms to become disordered. Conversely, as the temperature decreases, the material's ability to be magnetized increases. This law is generally applicable at high temperatures and in weak magnetic fields, where the thermal energy is dominant over the aligning force of the magnetic field.
