  • Eddy currents are loops of electric current induced within conductors by a changing magnetic field in the conductor, due to Faraday's law of induction.

    In a transformer core eddy currents are produced which heats  up the core and also causes losses by distorting the main current. If the core were a single piece its area would be high, and hence low resistance which causes a larger current to flow increasing the losses.

    If laminations are provided the area is reduced and hence resistance is very high which limits the current to a minimum value. The sum of current in all laminations would be still less than the case when a core was used.
