Query: Massive dual gauge field and confinement in Minkowski space : Magnetic
  charge   Gauge field configuration for a magnetic monopole and its dual configuration
are studied in SU(2) gauge theory. We present a relation between the monopole
field and its dual field. Since these fields can become massive, their massive
Lagrangians are derived. In the dual case, an additional term appears. We show
this term is necessary to produce a linear potential between a monopole charge
and an antimonopole charge.
