demagnetization energy
1adiabatic demagnetization — ▪ physics process by which the removal of a magnetic field from certain materials serves to lower their temperature. This procedure, proposed by chemists Peter Debye (Debye, Peter) (1926) and William Francis Giauque (Giauque, William… …
2Magnetic refrigeration — Gadolinium alloy heats up inside the magnetic field and loses thermal energy to the environment, so it exits the field cooler than when it entered. Magnetic refrigeration is a cooling technology based on the magnetocaloric effect. This technique… …
3Magnetization — This article is about magnetization as it appears in Maxwell s equations of classical electrodynamics. For a microscopic description of how magnetic materials react to a magnetic field, see magnetism. For mathematical description of fields… …
4Entropy (order and disorder) — Boltzmann s molecules (1896) shown at a rest position in a solid In thermodynamics, entropy is commonly associated with the amount of order, disorder, and/or chaos in a thermodynamic system. This stems from Rudolf Clausius 1862 assertion that any …
5magnet — /mag nit/, n. 1. a body, as a piece of iron or steel, that possesses the property of attracting certain substances, as iron. 2. a lodestone. 3. a thing or person that attracts: The park was a magnet for pickpockets and muggers. [1400 50; late ME… …
