The symbol commonly used for eddy current loss is \( P_{\text{ec}} \) or sometimes just \( P_{\text{eddy}} \). This represents the power loss in electrical devices, such as transformers, motors, or inductors, due to eddy currents. Eddy currents are loops of electric current induced within conductors when the conductor is exposed to a changing magnetic field.
So in an equation or a discussion, you'll often see something like:
\[
P_{\text{ec}} = \text{Eddy current losses}
\]
This loss is a result of the resistive heating caused by the circulating currents inside the material.
