WebBlog. Eddy current testing is a method of non-destructive testing, or NDT, that utilizes the process of electromagnetic induction for the evaluation and measurement of conductive materials without causing damage. Eddy … WebThe eddy currents are caused when the metal plate which is subjected to a magnetic field is take out rapidly. This causes current to flow within the metal plate and thus opposing the already existing magnetic field (Lenz's law).

WebThe eddy current loss is proportional to; Eddy Current loss (We) = K x I2 R (Where K is the eddy current constant) From above it is clear that the higher the current, the higher is the loss. The solid core has a larger cross-section area, therefore it has lower resistance. According to Ohm’s Law, the lower resistance causes a higher current ... In electromagnetism, eddy currents (also called Foucault's currents) are loops of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field. Eddy currents flow in closed loops … See more 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 … See more A magnet induces circular electric currents in a metal sheet moving through its magnetic field. See the diagram at right. It shows a metal sheet (C) moving to the right under a stationary magnet. The magnetic field (B, green arrows) of the magnet's north pole … See more • Stoll, R. L. (1974).
