Определение eddy current в Английский Язык Английский Язык словарь
An induced electric current formed within the body of a conductor when it is exposed to a time varying magnetic field; utilized in induction heating and in some braking and damping systems
Electrical current generated (and dissipated) in a conductive material (often a rotor shaft) when it intercepts the electromagnetic field of a displacement or proximity probe
-The current that is generated in a transformer core due to the induced voltage in each lamination It is proportional to the square of the lamination thickness and to the square of the frequency
an AC current setup near the surface of a conductor exposed to an electromagnetic field
Foucault current, localized current that develops within a conductor that is moving through a varying magnetic field (Electromagnetism)
A circular current of water, usually resulting from an obstruction, that develops when the main flow becomes separated from the bank
induced circulating currents in a conducting material that are caused by a varying magnetic field
An induced electric current circulating wholly within a mass of metal; called also Foucault current
Electrical current which is generated (and dissipated) in a conductive material in the presence of an electromagnetic field
Small circulating currents of electricity produced on the surface of metal by a transmitted electromagnetic field These currents then produce a secondary electromagnetic field that can be detected by the search coil receiver (resulting in inductive imbalance between the windings)
Circulating electrical currents that are induced in electrically conductive elements when exposed to changing magnetic fields, creating an opposing force to the magnetic flux Eddy currents can be harnessed to perform useful work (such as damping of movement), or may be unwanted consequences of certain designs, which should be accounted for or minimized
Currents that flow in a substance from variations in magnetic induction See also Lenz Effect Laminates are used to prevent eddy currents, which cause physical and electrical resistance in an alternator or transformer, therefore wasting power
Small circulating currents produced on the surface of metal by the transmitted electromagnetic field These currents then produce a secondary electromagnetic field which is then detected by the search coil receiver windings resulting in inductive imbalance between the windings
Small circulating electrical currents generated when an electromagnetic field contacts the surface of a metal object Secondary electromagnetic fields are generated by these currents and picked up by the searchcoil's receive windings This causes an inductive imbalance to occur between the transmit and receive windings which is relayed to the detector circuitry producing an audio or visual response
Closed loops of induced current set up in a piece of metal when there is relative motion between the metal and a magnetic field The eddy currents are in such direction that the resulting magnetic forces oppose the relative motion
electric currents induced in a conductor by a changing magnetic field or by motion of the conductor through a magnetic field One of the sources of concern about potential hazard to subjects in very high magnetic fields or rapidly varying gradient or main magnetic fields Can be a practical problem in the cryostat of superconducting magnets, in particular for localized spectroscopy Can be reduced by the use of shielded gradients
