The core of a transformer is laminated in order to
Answer: (D) reduce energy loss due to eddy currents
Concept. Eddy currents flow in closed paths in the core and waste energy as heat.
Step 1. Lamination. Thin insulated sheets break up these paths, greatly reducing eddy-current loss. (Hysteresis loss is reduced by using soft iron.)
Answer. Reduce energy loss due to eddy currents (Option D).
