Quizplus · Accepted Answer

Laminating the iron core of a transformer reduces eddy current losses. Eddy currents are loops of electrical current induced within the core by the changing magnetic field, and they cause energy to be lost as heat. Laminating the core into thin, insulated layers restricts the flow of these currents, thereby reducing the losses they cause.
