Magnetic force between two charged particles?


I know the gravitational force between two particles with masses m1, m2:



F=Gm1m2|r|2ˆr


And I know the electrical force between two particles with charges q1, q2:


F=Kq1q2|r|2ˆr


(r is the position vector of particle 2 from the referential of particle 1 and ˆr=r|r|)


I've been looking for an expression like these for the magnetic force since 2012... Then I found Physics Stack Exchange. Does anybody know if such formula exists?
