To improve efficiency of transformer the flux coupling b/w primary & secondary coil should be
Correct answer: B. Maximum
- A. Small
- B. Maximum
- C. May be small or may be maximum
- D. Zero
Explanation
This option states that the flux coupling between the primary and secondary coil should be at its maximum to improve efficiency. This is correct because a higher degree of flux coupling ensures better energy transfer between the coils.

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.
