WebMinimisation of Eddy Currents: Eddy currents may be minimised by using laminated core of soft iron. The resistance of the laminated core increases and the eddy currents are reduced and wastage of energy is also reduced. Application of Eddy Currents: WebSuch currents are called eddy currents or Foucault currents. The direction of current is given by Lenz’s law. The effect of eddy current depends on the resistance of the path through which it flows. Eddy current heat the metal and thus energy is wasted in the form of heat. Application of eddy currents 1.
