Eddy current fluid

The term eddy current comes from analogous currents seen in water in fluid dynamics, causing localised areas of turbulence known as eddies giving rise to persistent vortices. Somewhat analogously, eddy currents can take time to build up and can persist for very short times in conductors due to their inductance. WebPhase lag is a parameter of the eddy current signal that makes it possible to obtain information about the depth of a defect within a material. Phase lag is the shift in time …

WebApr 17, 2024 · Eddy Current Damping : This method is based on the production of electromagnetic torque. We know that whenever a conductor cuts the magnetic flux or whenever there is a rate of change of magnetic flux an emf is induced according to Faraday's law of electromagnetic induction. WebEddy current Flow meters (ECFMs) are constructed of three coils mounted coaxially on a bobbin. The primary coil is excited by an Alternating Current (AC) power source which then excites two additional secondary coils via mutual inductance. As a conductive fluid flows within the ECFM's magnetic field it will induce eddy currents that will alter the
