Laminated core in a transformer is used to reduce
Correct answer: A. Eddy current losses
- A. Eddy current losses
- B. Hysteresis losses
- C. iron losses
- D. heat losses due to resistance
Explanation
A is the correct answer . Laminating the core in a transformer is primarily done to reduce eddy current losses. The thin insulated layers in the laminated core minimize the circular current paths and, consequently, reduce energy losses due to eddy currents.

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.
