Eddy current flows in
WebWhen a conducting material is placed near the coiled loop of electric current, Eddy current flows in those loops with the change in magnetic fluxes. It can be introduced by the relative motion of the conductor and the electric current, or by a fluctuating magnetic field created using an Alternating Current (AC) of Electromagnet or with a ...
