"WebFeb 4, 2024 · Sometimes, the core may also experience losses because of eddy currents. These are generally smaller than hysteresis thanks to the usage of laminated iron, which minimizes eddy currents. Still, eddy current losses in the core may occur on the external surfaces, the sharp corners, or in some exposed parts, such as the clamping plates. " - Eddy and hysteresis losses
