Magnetic flux is a scalar product of _.
Correct answer: B. B and A
- A. B and V
- B. B and A
- C. B and I
- D. None of these options are correct
Explanation
Magnetic Flux Φ is the dot / scalar product of magnetic flux density B, and cross-sectional area of coil A. Therefore, Φ = B.A. Hence Option B is correct.

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.
