  We present simulations of one magnetic monopole interacting with multiple
magnetic singularities. Three-dimensional plots of the energy density are
constructed from explicit solutions to the Bogomolny equation obtained by
Blair, Cherkis, and Durcan. Animations follow trajectories derived from
collective coordinate mechanics on the multi-centered Taub--NUT monopole moduli
space. We supplement our numerical results with a complete analytic treatment
of the single-defect case.
