Does anyone know how either Lienard or Wiechert justified the (1-v/c) factor that appears in their potential formula for a moving charge?
clem said:The derivation is in many textbooks.
The (1 (+-) v/c) factor in the Lienard Wiechert potentials is a correction factor that takes into account the velocity of the source and the speed of light in the equations. It accounts for the fact that the electromagnetic fields created by a moving charged particle are different from those created by a stationary charged particle.
The (1 (+-) v/c) factor affects the Lienard Wiechert potentials by changing the shape and magnitude of the electromagnetic fields. It causes the fields to become distorted and shifted in the direction of motion of the source.
The (1 (+-) v/c) factor is important in the Lienard Wiechert potentials because it allows us to accurately calculate the electromagnetic fields generated by a moving charged particle. Without this correction factor, our calculations would not be as precise and would not match experimental results.
The (1 (+-) v/c) factor is a consequence of special relativity, which states that the laws of physics must be the same for all observers moving at constant velocities. This correction factor accounts for the differences in the electromagnetic fields observed by different observers moving at different speeds.
No, the (1 (+-) v/c) factor is only necessary in cases where the source of the electromagnetic fields is moving at a significant fraction of the speed of light. For stationary sources, the factor becomes equal to 1 and has no effect on the potentials.
