Out of the following options which one can be used to produce a propagating electromagnetic wave? (a) A chargeless particle (b) An accelerating charge (c) A charge moving at constant velocity (d) A stationary charge

Answer: (b). A stationary charge gives only a static E; a uniformly moving charge gives steady fields that move with it, so neither radiates. An accelerating charge produces time-varying E and B fields that sustain each other and travel outward. So the answer is (b) an accelerating charge.

Displacement Current, Maxwell's Equations & Production

Out of the following options which one can be used to produce a propagating electromagnetic wave?

Show answer and solution

Answer: (b)

A stationary charge gives only a static $E$ ; a uniformly moving charge gives steady fields that move with it, so neither radiates.
An accelerating charge produces time-varying $E$ and $B$ fields that sustain each other and travel outward.
So the answer is (b) an accelerating charge.
