Explanation

Laminated iron is utilized in AC circuits primarily to reduce eddy current losses. Eddy currents are loops of electrical current induced within conductors by a changing magnetic field, which cause energy dissipation as heat. Laminating the iron increases electrical resistance along the plane of the laminations, thereby limiting these currents and reducing associated losses.
