WebHowever, below its Curie temperature (T C or A 2) of 771 °C (1044K or 1420 °F), it becomes ferromagnetic. In the past, the paramagnetic form of α-iron was known as beta iron (β-Fe). ... Steel is typically austenitized at 900–1000 °C before it is quenched and tempered. In physics and materials science, the Curie temperature (TC), or Curie point, is the temperature above which certain materials lose their permanent magnetic properties, which can (in most cases) be replaced by induced magnetism. The Curie temperature is named after Pierre Curie, who showed that … See more Magnetic moments are permanent dipole moments within an atom that comprise electron angular momentum and spin by the relation μl = el/2me, where me is the mass of an electron, μl is the magnetic moment, and l is … See more Approaching Curie temperature from above As the Curie–Weiss law is an approximation, a more accurate model is needed when the temperature, T, approaches the material's Curie temperature, TC.

WebAccording to Curie’s Law, the magnetization in a paramagnetic material is directly proportional to the applied magnetic field. If the object is heated, the magnetization is viewed to be inversely proportional to the temperature. The law was discovered by the French physicist, Pierre Curie. Curie’s Law can be framed into an equation.
