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′)=q′4π ϵ0constant×1|r−r′|proximity

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

A(r,r′)=φ(r,r′)×1c2constant×dr′dtdislocation

A(r,r′)=μ0 q′4πconstant×1|r−r′|proximity×dr′dtdislocation

Functions for an ordered pair of point charges (q,q′)

A charge q subject to an electric scalar potential φ at (r,t) due to a point charge q′ at (r′,t′) has an electric potential energy of:

qφ(q,q′)(r,r′)=qq′4π ϵ0constant×1|r−r′|proximity

A charge q subject to a magnetic vector potential A at (r,t) due to a point charge q′ which had a velocity dr′dt at (r′,t′) has a potential momentum of:

qA(q,q′)(r,r′)=qφ(q,q′)(r,r′)×1c2constant×dr′dtdislocation

qA(q,q′)(r,r′)=μ0 qq′4πconstant×1|r−r′|proximity×dr′dtdislocation
