Minimal Coupling and the Magneto uid Uni cation

The dynamics of a relativistic, hot charged uid is expressed in terms of a hybrid magneto uid eld which uni es the electromagnetic eld with an appropriately dened but analogous oweld. In this uni ed eld, the uid experiences no net force. Suitably modi ed (due to temperature) minimal coupling prescription for particle dynamics may be invoked to a ect the transformation from the oweld (or the electromagnetic) to the magneto uid eld for the homentropic uids. An appropriate prescription for the general isentropic uids is also derived. A few consequences of the uni cation are worked out.
