Abstract The rotating comological midels such as charged dust Perfect fluid and magnetohydrodynamic (MHD)flow in general relativity have been treated by a numder of authors . Early ’Nork on rotating charged dust published in 1968 y De and Raychaudhuri (7], Som and Raychaudhuri [21J. They descri ed cylindrically symmetric space-time in which the Lorentz orce vanishes.

He obtained some classes of exact solutions for :ases characterized by the constant ratio of charge to mass .. Bonnor (1980) [3] examined the rigid rotation in the :ase where this ratio is a function of position. from 1983-1985 Wils and Van den Bergh studied the pro Ilem of rotating charged dust with rigid and differential ’otation [24] - [26], [28] - [31]. The problem of rotating perfect fluid has been formul ted by Hoenseloers and Vishveshwara in (1979) [9], and eferences there in, in stationary axially symmetric space ime. |
