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:
“The force of the blow depends on the resistance. It is sometimes better not to struggle against temptation. Either fly or yield at once.”
—F.H. (Francis Herbert)
“Of course Im a black writer.... Im not just a black writer, but categories like black writer, woman writer and Latin American writer arent marginal anymore.
