The magnetic flux linked with a coil is inversely proportional to the:
Correct answer: D. None of these options is correct
- A. Area of cross-section
- B. Number of turns
- C. Magnetic field
- D. None of these options is correct
Explanation
The magnetic flux linked with a coil is directly proportional to the number of turns in the coil. When a coil has multiple turns, each turn contributes to the magnetic flux. The more turns a coil has, the more magnetic flux is linked with the coil.

About Magnetic Flux
Magnetic flux measures the magnetic field passing through a surface, calculated for a uniform field as Φ = BA cos θ, where θ is the angle between the field and the surface normal. Questions involve area, field strength and orientation, the weber as its unit, and the distinction between flux and magnetic field.
