The magnetic flux (ø) linked with a coil is related to the number of turns (N) of the coil as:
Correct answer: A. f∝N
- A. f∝N
- B. f∝N-1
- C. f∝N2
- D. f∝N-2
Explanation
The magnetic flux ø is directly related to the number of turns of the coil N.Flux = BA cos(θ)And B = uo n IHence flux = uo n I A cos(θ)Hence they are directly proportional.

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.
