  We extend the Myers dielectric effect to configurations with angular
momentum. The resulting time-dependent N D0 brane bound states can be
interpreted as describing rotating fuzzy ellipsoids. A similar solution exists
also in the presence of a RR magnetic field, that we study in detail. We show
that, for any finite N, above a certain critical angular momentum is
energetically more favorable for the bound state system to dissociate into an
abelian configuration of N D0 branes moving independently. We have investigated
this problem in the low-energy expansion of the non-abelian D brane action for
generic N. In the case N=2 we find explicit solutions of the full non-abelian
Born-Infeld D brane dynamics, which remarkably have the same structure and
confirm the features of the low-energy approximation. We further study D string
configurations representing fuzzy funnels deformed by the magnetic field and by
the rotational motion.
