The core used in transformers are laminated to (a) increase the magnetic field. (b) increase the level of the magnetic saturation of the core. (c) reduce the residual magnetism in the core. (d) reduce eddy current losses in the core.

Answer: (d). A solid core carries large circulating eddy currents, which waste energy as heat. Thin insulated laminations break these current paths and increase resistance. So the answer is (d) reduce eddy current losses in the core.
