Magnetic flux is a _ product.
Correct answer: A. Scalar
- A. Scalar
- B. Vector
- C. Simple
- D. None of these
Explanation
As we are using dot products, the magnetic flux is a scalar quantity. Note: When the magnetic field is along the area of the closed surface, the magnetic flux is 0. It happens because the angle between the area vector and the magnetic field vector is 90°.

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.
