Lamination is used in a transformer in order to:
Correct answer: D. Minimize eddy current
- A. Reduce flux leakage
- B. Minimize hysteresis loss
- C. Decrease coil resistance
- D. Minimize eddy current
Explanation
Laminations are specifically designed to minimize eddy currents by breaking up the metallic core into insulated sheets. These sheets reduce the circular current flow, lowering eddy current losses in the core.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
