Retarded vector magnetic potential

WebMagnetic scalar potential, ψ, is a quantity in classical electromagnetism analogous to electric potential.It is used to specify the magnetic H-field in cases when there are no free currents, in a manner analogous to using the electric potential to determine the electric field in electrostatics.One important use of ψ is to determine the magnetic field due to …
