magnetocaloric effect [mag¦nēd·ō·kə′lȯr·ik i‚fekt] (thermodynamics) The reversible change of temperature accompanying the change of magnetization of a ferromagnetic material. Magnetocaloric effect The reversible change of temperature accompanying the change of magnetization of a ferromagnetic or paramagnetic material. This change in temperature may be of the order of 1°C (2°F), and is not to be confused with the much smaller hysteresis heating effect, which is irreversible.

Magnetic refrigeration is based on the magnetocaloric effect -- the ability of some metals to heat up when magnetized and cool down when removed from the magnetic field. Like its superconducting predecessor, the new unit takes advantage of the so-called magnetocaloric effect. |
