The magnetic properties of the Sun's polar faculae are investigated withspectropolarimetric observations of the north polar region obtained by theHinode satellite in 2007 September. Polar faculae are embedded in nearly allmagnetic patches with fluxes greater than $10^{18}$ Mx, while magnetic patcheswithout polar faculae dominate in the flux range below $10^{18}$ Mx. Thefaculae are considerably smaller than their parent patches, and single magneticpatches contain single or multiple faculae. The faculae in general have higherintrinsic magnetic field strengths than the surrounding regions within theirparent patches. Less than 20% of the total magnetic flux contributed by thelarge (${\ge}10^{18}$ Mx) concentrations, which are known to be modulated bythe solar cycle, is accounted for by the associated polar faculae.
