Does it make any sense to think that a very large number of electrons
(billions) can stay together (despite the mutual repulsion) when they
circulate rapidly forming a small "toroidal vortex?" The nonuniform
magnetic field, created by them, is said to produce confining forces.
It would be like a large "classical" atom without a nucleus (a cluster
of charges, if you prefer).
