We discuss the calculation of the strange magnetic radius of the proton in chiralperturbation theory. In particular, we investigate the low-energy component of the loopintegrals involving kaons. We separate the chiral calculation into a low-energy part and ahigh-energy component through use of a momentum space separation scale. This separationshows that most of the chiral calculation comes from high energies where the effectivefield theory treatment is not valid. The resulting low-energy prediction is in betteragreement with dispersive treatments. Finally, we briefly discuss magnetic moments andshow how our techniques can help resolve an old puzzle in understanding the magneticmoments of the proton and face="symbol">S+.
