  The strangeness contribution to the nucleon magnetic moment is calculated at
the one-loop level in a relativistic SU(3) chiral potential model and is found
to be {\em positive}, that is, with an {\em opposite} sign to the nucleon
strangeness polarization. It is the ``Z'' diagram that violates the usual
relation between spin and magnetic moment. The positive value is due to the
contribution from the intermediate excited quark states, while the intermediate
ground state gives a negative contribution. Our numerical results agree quite
well with the new measurement of the SAMPLE Collaboration.
