Hysteresis Loss and Eddy Current Loss: What's the Difference?
Hysteresis loss is caused by the magnetization and demagnetization of the core as current flows in the forward and reverse directions. As the magnetizing force (current) increases, the magnetic flux increases. But when the magnetizing force (current) is decreased, the magnetic flux doesn’t decrease at the same rate, but less gradually.
Eddy current losses are the result of Farady’s law, which states that, “Any change in the environment of a coil of wire will cause a voltage to be induced in the coil, regardless of how the magnetic change is produced.”
How to Calculate Average Hysteresis Power Loss?
Average Hysteresis Power Loss calculator uses Hysteresis Loss = Hysteresis Constant*Frequency*(Magnetic Flux Density)^Steinmetz Coefficient to calculate the Hysteresis Loss, The Average Hysteresis Power Loss formula is defined as the energy entrapped in magnetic materials exposed to a magnetic field in the form of residual magnetization. Hysteresis Loss is denoted by P_{hystersis} symbol.
