eddy current loss

Eddy current loss refers to the loss of energy that occurs in electrical machinery and transformers due to eddy currents. Eddy currents are electrical charges that move within a conducting material, induced by a changing electric or magnetic field.12

These induced currents create heat, which represents a loss of power and is generally undesirable in applications like transformer cores. However, eddy currents can also be harnessed for useful purposes, such as generating heat for cooking or in metallurgical furnaces. Minimizing eddy current loss is crucial for the efficiency of electrical devices, and methods like using thinner laminations in transformer cores help reduce this effect.23
