How can eddy current loss be minimised
WebThe iron or core losses can be minimized by using silicon steel material for the construction of the core of the transformer. Eddy Current Loss When the flux links with a closed circuit, an emf is induced in the circuit and the current flows, the value of the current depends upon the amount of emf around the circuit and the resistance of the circuit.
