Magnetic fields are solenoidal fields
WebOct 10, 2008 · The analytic studies show that the solenoidal magnetic field starts to infuence the self-electric and self-magnetic fields when ωce > ωpeβb, where ωce = eβ/mec is the electron gyrofrequency, ωpe is the electron plasma frequency, and βb = Vb/c is the ion beam velocity relative to the speed of light. WebOct 8, 2024 · Nothing is special to the magnetic field. The decomposition holds for all solenoidal fields. I suspect your conjecture is correct, but I don't know how to construct the (scalar) potentials for D=4, the way construction is standard for D=3. Perhaps the MSE is friendlier to this type of question. – Cosmas Zachos Oct 8, 2024 at 19:43

This ... WebSep 4, 2024 · Solenoidal fields are characterized by their so-called vector potential, that is, a vector field A such that a=curlA. Examples of solenoidal fields are field of velocities of an incompressible liquid and the magnetic field within an infinite solenoid. When a velocity field is irrotational?
One important property of the B-field produced this way is that magnetic B-field lines neither start nor end (mathematically, B is a solenoidal vector field); a field line may only extend to infinity, or wrap around to form a closed curve, or follow a never-ending (possibly chaotic) path.
