During the circular path in magnetic field, what is the magnetic force?
Correct answer: D. F = qvB
- A. F = Qb
- B. F = qB2
- C. F = qB/v
- D. F = qvB
Explanation
This is a standard answer. A charged particle moving perpendicular to a constant magnetic field experiences a magnetic force F, which causes it to move in a circular path. The formula for this magnetic force is Bvq.

About Charged Particle in a Magnetic Field
A charged particle moving through a magnetic field experiences the Lorentz force, which is perpendicular to both its velocity and the field. The motion may be circular or helical, with questions involving radius, angular frequency, time period, and work done. A stationary charge feels no magnetic force.
