  A self-dual, localized solution to the classical SU(2) Yang-Mills equation in
Euclidean spacetime, which formally possesses infinite action, is investigated
in view of its U(1) charge content after Abelian projection. This is suggested
by noting that the solution satisfies 't Hooft's differential projection
condition away from the singularities. As a result the existence of dynamical,
magnetic charge of finite lifetime is established. A covariant cutoff for the
action is introduced by demanding the solution to be close to an instanton
topologically. This is in analogy to the \underline{calculation} of the mass of
a point charge in classical electrodynamics or the subtraction of diverging
self-energies of magnetic monopoles as discussed in the literature. The Wilson
loop is evaluated in the background of a dilute gas. Assuming identical
integrals over size distributions, the corresponding static quark/anti-quark
potential at infinite spatial separation can be seizably higher than the
potential in a dilute instanton gas.
