Curie's Law:In a paramagnetic material the magnetization of the material is directly proportional to an applied magnetic field. However, if the material is heated, the magnetization is inversely proportional to temperature.i.e. M = C x ( B / T )where, M is the magnetisationB is the magnetic field, measured in teslasT is absolute temperature, measured in kelvinsC is a material-specific Curie constantIt was first discovered experimentally by French physicist, Pierre Curie. It holds for high temperatures, or weak magnetic fields.
