The transformer laminations are insulated from each other by?
Correct answer: C. Thin coating of Varnish
- A. Mica strip
- B. Paper
- C. Thin coating of Varnish
- D. Any of the above
Explanation
These laminations are insulated from each other by a "thin coat of varnish" or paper to increase the effective resistivity of the core, thereby increasing the overall resistance to limit the flow of the 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.
