Answer» <p>Thecoreislaminatedto reduce these to a minimum as they interfere with the efficient transfer of energy from the primary coil to the secondary one. </p><p>The eddy currents cause energy to be lost from thetransformeras they heat up thecore- meaning that electrical energy is being wasted as unwanted heat energy.</p><p>The answer is energy losses due to eddy currents may be minimised.</p>
