Chapter 36, Problem 12A

To determine

To explain: The charged particle experiencing the magnetic force

Explanation of Solution

Introduction:

The magnetic force which is acted on the charged particle is in the perpendicular direction to the magnetic field, which is represented as,

  $\mathrm{F}=qVBsin\theta$

Where, $\theta$ is the angle between the magnetic force and magnetic field.

To experience the magnetic force, the charged particle must be moving. The magnetic field vector is perpendicular to the charged particle’s magnetic force and it depends upon the particle’s velocity.

Conclusion:

Hence, to experience the magnetic force by the charged particle, it must be moving to experience it.
