Magnetic flux is the dot product of:
Correct answer: B. Magnetic field and vector area
- A. Magnetic field and scalar area
- B. Magnetic field and vector area
- C. Magnetic field per unit scalar area
- D. Magnetic field per unit vector area
Explanation
The physical description of magnetic flux through a surface is the surface integral of the scalar product (dot product) of the magnetic field vector (B) and elementary area vector (dA).

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.
