The magnetic flux (Φ) 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∝1/N
- C. f∝1(N)2
- D. f∝N2
Explanation
Magnetic flux is denoted by ΦB The magnetic flux value depends on the magnetic field direction and it is a vector quantity.The magnetic flux formula is given byΦ B =N B ⋅ A. [ where N is number of turns] Φ B =N B A c o s θHence, flux f ∝ N

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.
