  P-vortices, in an SU(N) lattice gauge theory, are excitations on the
center-projected Z(N) lattice. We study the ratio of expectation values of
SU(2) Wilson loops, on the unprojected lattice, linked to a single P-vortex, to
that of Wilson loops which are not linked to any P-vortices. When these ratios
are plotted versus loop area in physical units, for a range of lattice
couplings, it is found that the points fall approximately on a single curve,
consistent with scaling. We also find that the ratios are rather insensitive to
the point where the minimal area of the loop is pierced by the P-vortex.
