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?
