Eddy currents are localized, circulating electrical currents induced within a conductor by a time-varying magnetic field. This phenomenon is a direct result of electromagnetic induction, where the changing magnetic flux passing through a material generates an electromotive force within the conductive structure. The magnitude of these induced currents is generally proportional to the conductivity of the material and the rate of change of the magnetic field. These currents can cause significant energy losses through resistive heating, a property utilized in various technological applications such as non-destructive testing, which detects internal material flaws, or in electromagnetic damping systems that reduce unwanted mechanical vibrations by dissipating energy.
