Increased lattice vibration impedes the flow of electron. This in turn, increases temperature and resistance occurs. So, the temperature is a form of heat energy loss. Eddy current caused by EMF leads to energy loss. When revising, I seem to get confused with the differences and mix Eddy current and Resistance up. Both occur energy loss so what is the difference which differentiate Resistance and Eddy current? Aren't they the same physics principle? When do each occur? Thanks in advance.
