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 alternating magnetic field. The flow of current induced by this magnetic field in the conductive material will generate a magnetic field by itself in opposition ...
Eddy current definition is; the flow of current that is induced in any solid conducting body once the magnetic flux is supplied throughout it. Once the conductor encounters a change within the magnetic flux, then the free electrons present in the conductor will experience a magnetic force.
So this is used in aerospace, power & petrochemical-based industries for detecting damages & metal cracks. 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 alternating magnetic field.
Eddy currents in conductors of non-zero resistivity generate heat as well as electromagnetic forces. The heat can be used for induction heating. The electromagnetic forces can be used for levitation, creating movement, or to give a strong braking effect. Eddy currents can also have undesirable effects, for instance power loss in transformers.
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.
The advantages of eddy current include the following. The process of Eddy current is very helpful in the inspection process. Eddy current is a non-contact inspection procedure that does not have an effect on the work. Inspection through this process is an accurate & very fast procedure. Less maintenance is required for its breaks.
Thus eddy currents are a cause of energy loss in alternating current (AC) inductors, transformers, electric motors and generators, and other AC machinery, requiring special construction such as laminated magnetic cores or ferrite cores to minimize them.

In electromagnetism, an eddy current (also called Foucault''s current) is a loop 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.
This current that drives inside nearby ferrous elements is called an eddy current, and it appears inside the iron core itself. The release of the magnetic field attempts to drive current in a small circuit inside the iron itself, which is a conductive metal. Eddy currents can also appear in chunks of metal near the transformer or ...
In addition, eddy current equipment is portable, with most systems using battery power. Eddy current applications are best suited for inspecting small localized areas. Scanning large areas for randomly oriented cracks is discouraged unless the system is automated. Eddy current can be more economical than other methods, because stripping and refinishing of surface coatings is …
