Which of the following is a vector quantity?
Correct answer: A. Magnetic flux density
- A. Magnetic flux density
- B. Magnetic field lines
- C. Magnetic flux
- D. Both A and B
Explanation
Magnetic flux density (B) is a vector quantity because it has both magnitude and direction. Magnetic flux (Φ) is a scalar quantity, and magnetic field lines are just a visual representation, not a vector quantity themselves.

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.
