The confinement in compact QED is known to be related to magnetic mono
poles. Magnetic currents form a solenoid around electric flux lines be
tween a pair of electric charges. This behaviour can be described by t
he dual version of Maxwell-London equations including a fluctuating st
ring. We use a definition of magnetic monopole currents adjusted to th
e definition of the electric field strength on a lattice and get good
agreement for field and current distributions between compact QED and
the predictions of dual Maxwell-London equations. Further we show that
the monopole fluctuations in the vacuum are suppressed by the flux tu
be.
