Jefimenko's Equations

Jefimenko's Equations describe how electric and magnetic fields are generated and change over time by charges and currents. They show that these fields are influenced not just by the current positions of charges, but also by how they move and accelerate, taking into account the time it takes for effects to travel at the speed of light. Essentially, these equations detail the cause-and-effect relationship between moving charges and the resulting electric and magnetic fields, providing a complete picture of electromagnetic phenomena consistent with Einstein’s theory of relativity.
