WebHow does an eddy current sensor work? Eddy current sensor operating principle. Eddy current sensors utilize the principle of eddy current formation to determine the displacement. It forms when a changing magnetic field intersects a conductor. The relative movement causes a circulating stream of electrons, or electrons, in the conductor. WebThe eddy currents are concentrated at the surface of the material. The reason is that at high frequency, the imposed magnetic field changes its direction very fast. Therefore, the induced currents in one direction do not have enough time to penetrate into the depth of the metal before their time is up.
