Iron loss-When an electric current flows through a copper conductor (or any conductor), some energy is converted to heat. i(square)*r...this equation is obvious that iron loss depends on flowing current.
Core loss-Magnetic loss...composed of hysterisis loss,eddy current loss...
Doesnt depend on electrical component....The losses same even with or without load. hence know as constant losses.
