We present results for the {\em dynamical}\/ magnetic susceptibility of the
t-J model, calculated with the dynamical mean field theory. For J=0 we
find enhanced ferromagnetic correlations but an otherwise relatively
q-independent dynamical magnetic susceptibility. For J>0 the explicit
antiferromagnetic exchange leads to a dynamic spin structure factor with the
expected peak at the antiferromagnetic Bragg point.Comment: 3 pages LaTeX, postscript figures included, submitted as contribution
