The magnetic force acting on a unit positive charge moving perpendicular to the magnetic field with a unit velocity is called:
Correct answer: B. Magnetic field intensity
- A. Magnetic flux
- B. Magnetic field intensity
- C. Magnetic induction
- D. Self inductance
Explanation
The formula for magnetic force is F=Bqv. Manipulating this equation to get B=F/qv substantiates B as the answer.

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.
