What is eddy current? What are the disadvantages of eddy current generation?
When an alternating current passes through a wire, an alternating magnetic field is generated around the wire. The inside of the whole conductor in the alternating magnetic field will generate an induced current. Since this induced current forms a closed loop inside the whole conductor, much like a water vortex, it is called an eddy current. Eddy current will not only waste electric energy in vain, reduce the efficiency of using electrical equipment, but also cause heating of electrical appliances (such as transformer iron core), which will affect the normal operation of equipment in severe cases.
