The core used in transformer and other electromagnetic devices is laminated to (a) increase the magnetic field. (b) increase the level of magnetic saturation of the core. (c) reduce the residual magnetism in the core. (d) reduce eddy current.

Answer: (d). Changing flux induces eddy currents in a solid core. Insulated laminations cut the eddy current paths, reducing them. So the answer is (d) reduce eddy current.
