Basic.LeakageWithCoefficient accounts for leakage not by the geometry of flux tubes, but by a coupling coefficient c_usefulFlux.
The permeances of all elements of this package are calculated from their geometry [Ro41]. These flux tube elements are intended for modelling of leakage fields through vacuum, air and other media with a relative permeability
