Lamination of the transformer core is made of
Correct answer: B. Silicon steel
- A. Cast iron
- B. Silicon steel
- C. Aluminium
- D. Cast steel
Explanation
Eddy currents passing through the core of a transformer due to the induced voltages can cause heat loss. This heat loss is reduced significantly by silicon steel lamination of 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.
