Answer 2

Answer:

Step-by-step explanation:

The electromagnetic four-potential:

A relativistic vector function that may be used to determine the electromagnetic field is called an electromagnetic four-potential. It creates a single four-vector by combining a magnetic vector potential with an electric scalar potential.

The electric scalar potential is often considered to be the first component of the electromagnetic four-potential, while the magnetic vector potential is made up of the remaining three components as measured in a particular frame of reference and for a certain gauge. While the frame affects both the scalar and vector potentials, the electromagnetic four-potential is Lorentz covariant.

Numerous distinct electromagnetic four-potentials, depending on the gauge selection, correspond to the same electromagnetic field, just as other potentials.

Option (A) is the answer.

The component A of four potential A' of electromagnetic field describes

(A) vector potential of the electromagnetic field.
