Lorentz Force in Terms of Potentials
See also: Mathematical descriptions of the electromagnetic field, Maxwell's equations, and Helmholtz decompositionThe E and B fields can be replaced by the magnetic vector potential A and (scalar) electrostatic potential ϕ by
where ∇ is the gradient, ∇• is the divergence, ∇ × is the curl.
The force becomes
and using an identity for the triple product simplifies to

Famous quotes containing the words force and/or terms:
“An artist is only an ordinary man with a greater potentiality—same stuff, same make up, only more force. And the strong driving force usually finds his weak spot, and he goes cranked, or goes under.”
—D.H. (David Herbert)
“The research on gender and morality shows that women and men looked at the world through very different moral frameworks. Men tend to think in terms of “justice” or absolute “right and wrong,” while women define morality through the filter of how relationships will be affected. Given these basic differences, why would men and women suddenly agree about disciplining children?”
—Ron Taffel (20th century)
