| electromagnetic coupling | <physics> A means of extracting energy from a magnetically confined plasma, where the plasma expands and pushes on the confining magnetic field, causing electrical energy to be generated in the external field-generating circuits. (09 Oct 1997) |
|---|
| electromagnetic | <physics> Of, Pertaining to, or produced by, magnetism which is developed by the passage of an electric current. Electromagnetic engine, an engine in which the motive force is electromagnetism. Electromagnetic theory of light, a theory of light which makes it consist in the rapid alternation of transient electric currents moving transversely to the direction of the ray. (03 Mar 1998) |
|---|---|
| electromagnetic fields | Fields representing the joint interplay of electric and magnetic forces. (12 Dec 1998) |
| electromagnetic flowmeter | A flowmeter in which a magnetic field is applied to a blood vessel to measure flow in terms of the voltage developed by the blood as a conductor moving through the magnetic field. (05 Mar 2000) |
| electromagnetic force | <physics> One of the fundamental forces of interaction which influences charged entities. In quantum field theory, the electromagnetic force is mediated by particles of exchange called (virtual) photons. Photons are massless and travel at the speed of light c. The electromagnetic force obeys an inverse square law, which makes sense because it is mediated by particles that have an infinite lifetime (special-relativistically, time stops in a frame moving at c when observed from a non-moving frame). (05 Jan 1998) |
| electromagnetic induction | Electromagnetic waves propagated by induction in an electromagnetic field. (05 Mar 2000) |
| electromagnetic lens | <apparatus> An electromagnet designed to produce a suitably shaped magnetic field for the focusing and deflection of electrons or other charged particles in electron optical instruments (cf. Electrostatic lens.) See: microscope, electron. (05 Aug 1998) |
| electromagnetic radiation | <physics> Radiation (such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays) which consists of associated, interacting electric and magnetic field waves which travel at the speed of light. All forms of electromagnetic radiation can be transmitted through vacuum. Electromagnetic waves in plasmas are generally more complex in their behaviour, depending on their frequency. (09 Oct 1997) |
| electromagnetic unit | The unit in an absolute system (CGS) of unit's utilizing the magnetic effects of current; e.g., abampere, abfarad, abhenry, abohm, abvolt. (05 Mar 2000) |
| electromagnetic wave | <physics> A wave of electric and magnetic fields that can move through space. Particles which make up the waves are called photons. (09 Oct 1997) |
| viscous mechanical coupling | <cell biology> Method by which adjacent cilia are synchronised in a field. Coupling is through the transmission of mechanical forces, rather than of a synchronising signal. (18 Nov 1997) |
| chemiosmotic coupling | The linking of ATP synthesis to electrontransfer by way of an electrochemical hydrogen cation gradient across amembrane. (09 Oct 1997) |
| metabolic coupling | <cell biology, molecular biology> Transfer between tissue cells in contact of low molecular weight metabolites such as nucleotides and amino acids. Transfer is via channels constituted by the connexons of gap junctions and does not involve exchange with the extracellular medium. First observed in cultures of animal cells in which radio labelled purines were transferred from wild type cells to mutants unable to utilise exogenous purines. (27 Jun 1999) |
| constant coupling | Where several premature beats are seen, the interval between each of them and the preceding normal beat is constant. Synonym: constant coupling. Variable coupling, where several extrasystoles are seen, the interval between each of them and the preceding sinus beat varies. (05 Mar 2000) |
| coupling | <biochemistry> The linking of two independent processes by a common intermediate, for example the coupling of electron transport to oxidative phosphorylation or the ATP ADP conversion to transport processes. (18 Nov 1997) |
| coupling defect | See: familial goiter. (05 Mar 2000) |
