1.4 Eddy Current Loss
Eddy-current loss is caused by small currents circulating within the core
material, stimulated by the alternating flux in the core.
The I2R power loss associated with these currents produces
heating of the core known as eddy current loss.
In iron cored transformers, insulated iron sheets known as laminations
are used to minimise this effect, by restricting the path for circulating
Ferrite cores restrict these paths even further.
