Very strong magnetic fields can arise in non-central heavy-ion
collisions at ultrarelativistic energies, which may not decay quickly in a
conducting plasma. We carry out magnetohydrodynamics
simulations to study the effects of this magnetic field on the evolution
of the plasma and on resulting flow fluctuations. Our results show that
magnetic field leads to enhancement in elliptic flow, while flow fluctuations
lead to reorganization of magnetic flux resulting in a transient increase
in the local magnetic field. We also show generation of vorticity arising
from nontrivial dependence of magnetosonic waves on pressure gradients and
magnetic field direction. Magnetic field from collision of deformed nuclei shows very nontrivial features and can lead to qualitatively
new effects on plasma evolutions. We discuss possibility of dynamo effect
in the presence of vortices if any exotic high baryon density QCD phases
are achieved in heavy-ion collisions.
