Eddy current: The

The ‘statically’ induced EMF and currents When there is no relative spatial motion or movement between the magnetic field and the medium, both being ‘stationary’ in space, but the former is changing with time, for example that produced by an alternating current as in Fig.1.2(b), the induced EMF follows directly from the second law of Faraday. This can mathematically be expressed by dØ e = (1.3) dt where Ø is the time-varying magnetic field to which the medium is exposed. The above ... The main properties of eddy currents are; these are only induced within the conducting materials, they are distorted by different defects like corrosion, edges, cracks, etc. So this is used in aerospace, power & petrochemical-based industries for detecting damages & metal cracks. Eddy Current Working Principle The eddy current working principle is to generate eddy currents within a conductive material. So this can be achieved by connecting a coil to an AC generator which drives an ... What is Eddy Current or What is Eddy Current's Principle? Eddy current is a current , which is circulate in conductors.
