The charged particle is situated in a region of space and it experiences a force only when it is in motion. It can be deduce that the region encloses
Correct answer: C. A magnetic field only
- A. Both electric and magnetic field
- B. Both magnetic and gravitational field
- C. A magnetic field only
- D. An electric field only
Explanation
The definition of magnetic field: The region where a moving charge particle experiences a force, provided that it moves perpendicular to the magnetic field. Only the magnetic field requires the particle to be in motion, while electric and magnetic fields can exert a force on a stationary object as well.

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.
