Abstract
The Lagrangian for the motion of n well-separated BPS monopoles is cal culated by treating the monopoles as point particles with magnetic, el ectric and scalar charges. It can be reinterpreted as the Lagrangian f or geodesic motion on the asymptotic region of the n-monopole moduli s pace, thereby determining the asymptotic metric on the moduli space. T he metric is hyperkahler, and is an explicit example of a type of metr ic considered previously.
