Core losses or Iron losses: These losses having of hysteresis and eddy current losses, which happen due to pulsation of flux in the core. These losses depend upon the maximum flux density in the core and frequency. Since from no load to full load the flux connecting with core and frequency remains constant so these losses remain constant.
Explain Thermal Physics and Quanmtum mechanics Thermal Physics , in which one studies the nature of heat and the changes that the addition of heat brings about in matter.
