The physics of moving charge particles is known as__________?
Correct answer: D. Electro-dynamics
- A. Plasma physics
- B. Electro-static's
- C. Electro-magnetic
- D. Electro-dynamics
Explanation
Electrodynamics deals with electric charges in motion and the electric and magnetic fields associated with them. Electrostatics is the likely alternative because it also studies electric charges, but it is restricted mainly to charges at rest.

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.
