41materials science — the study of the characteristics and uses of various materials, as glass, plastics, and metals. [1960 65] * * * Study of the properties of solid materials and how those properties are determined by the material s composition and structure, both… …
42Electromagnet — An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current is turned off. Electromagnets are widely used as components of other electrical devices,… …
43List of fictional elements, materials, isotopes and atomic particles — This list contains chemical elements, materials, isotopes or (sub)atomic particle that exist primarily in works of fiction (usually fantasy or science fiction). No actual periodic elements end in ite , though many minerals have names with this… …
44EmDrive — (also Relativity Drive) is the name of a spacecraft propulsion system proposed, and reportedly developed, by Roger Shawyer.cite news|title=Relativity drive: The end of wings and wheels?|date=2006 09 08|author=Justin Mullins|issue=2568|work=New… …
45Pi Josephson junction — A pi Josephson Junction is a specific instance of a Josephson Junction where the Josephson phase phi is equal to pi in the ground state, i.e. when no external currents or magnetic fields are applied to the Josephson junction. Background The… …
46History of superconductivity — The history of superconductivity , the property exhibited by certain substances of lacking electrical resistance at temperatures close to absolute zero, began at the end of the 19th century and culminated in Heike Kamerlingh Onnes s 1911… …
47Cryotron — For the gas filled tube, see Krytron. The cryotron is a switch that operates using superconductivity. The cryotron works on the principle that magnetic fields destroy superconductivity. This simple device consists of two superconducting wires ( e …
48Reversed field pinch — A reversed field pinch (RFP) is a device used to produce and contain near thermonuclear plasmas. It is a toroidal pinch which uses a unique magnetic field configuration as a scheme to magnetically confine a plasma, primarily to study magnetic… …
49Degaussing — Degausser redirects here. For the song by Brand New, see Degausser (song). Degaussing is the process of decreasing or eliminating an unwanted magnetic field. It is named after Carl Friedrich Gauss, an early researcher in the field of magnetism.… …
50Magnetometer — A magnetometer is a measuring instrument used to measure the strength or direction of a magnetic field either produced in the laboratory or existing in nature. Some countries such as the USA, Canada and Australia classify the more sensitive… …
