Eddy Current Loss: Eddy current loss refers to the energy dissipated as heat within a conductive material when it's subjected to a changing magnetic field. These changing fields induce circulating electric currents, known as "eddy currents," within the material itself. Because these currents do no useful work and encounter resistance, they lead to an I2R power loss, which is manifested as heat. This phenomenon is a significant concern in AC machines like transformers, motors, and generators, impacting their efficiency. To minimize eddy current losses, manufacturers often use laminated cores (thin, insulated sheets) and materials with higher electrical resistivity.
