Abstract
|
We consider a class of magnetic fields defined over the interior of a manifold
which
go to infinity at its boundary and whose direction near the boundary of
is controlled by
a closed 1-form
.
We are able to show that charged particles in the interior of
under
the influence of such fields can only escape the manifold through the zero locus of
. In
particular in the case where the 1-form is nowhere vanishing we conclude that the
particles become confined to its interior for all time.
