Magnetic flux density is a:
Correct answer: B. Vector quantity
- A. Scalar quantity
- B. Vector quantity
- C. Sometimes scalar sometimes vector
- D. None of these
Explanation
Magnetic flux density is a vector quantity. It has both magnitude and direction. The magnitude of the magnetic flux density is measured in teslas (T). The direction of the magnetic flux density is the direction of the magnetic field. The magnetic flux density is the dot product of the magnetic field vector and the area vector. The magnetic field vector is the vector that describes the direction and strength of the magnetic field. The area vector is the vector that describes the area of the surface that is being considered. The magnetic flux density is sometimes confused with magnetic flux, which is a scalar quantity. Magnetic flux is the amount of magnetic field that passes through a surface. It is measured in webers (Wb).

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.
