The strange magnetic form factor of the nucleon is studied in the heavybaryon chiral effective approach at next to leading order. The one loopcontributions from kaon and intermediate octet and decuplet hyperons areincluded, using finite-range-regularization to deal with the ultra-violetdivergences. Drawing on an established connection between quenched and fullQCD, this model makes it possible to predict the strange magnetic form factorunder the hypothesis that for a dipole regulator mass $\Lambda$ around 0.8 GeV,strangeness in the core is negligible. The strange magnetic form factor isfound to be small and negative over a range of momentum transfer, while thestrange magnetic moment is consistent with the best lattice QCD determinations.
