The electrostatic force between two point charges with a given separation is given by Coulomb's law (F=Q1*Q2/4π*r²*ε0). ε0 is the vacuum permittivity. The integration of this force over distance gives the potential energy of the system.

Magnetic force between wires

Currents flowing through wires create magnetic fields. This results in the attraction or repulsion of parallel wires according to Ampere's force law (given by F=μ*I1*I2*l/2π*r).
