Functions for a point charge q

The electric scalar potential φ at (r,t) due to a point charge q at (r,t) is:

φ(r,r)=q4π ϵ0constant×1|rr|proximity

The magnetic vector potential A at (r,t) due to a point charge q which had a velocity v at (r,t) is:

A(r,r)=φ(r,r)×1c2constant×drdtdislocation

A(r,r)=μ0 q4πconstant×1|rr|proximity×drdtdislocation
