  We present an analytic and parameter-free expression for the momentum
dependence of the strange magnetic form factor of the nucleon and its
corresponding radius which has been derived in Heavy Baryon Chiral Perturbation
Theory. We also discuss a model-independent relation between the isoscalar
magnetic and the strange magnetic form factors of the nucleon based on chiral
symmetry and SU(3) only. These limites are used to derive bounds on the strange
magnetic moment of the proton from the recent measurement by the SAMPLE
collaboration.
