Why is the core of a transformer laminated?
ATo reduce weight
BTo increase magnetic flux
CTo minimize eddy current loss
DTo prevent rusting
✓ Correct Answer: C — To minimize eddy current loss
Lamination breaks the path for eddy currents, which are small circular currents that cause heating and power loss in the core.
