Two cases have been examined out of which one reduces to isotropic sphere. The solutions thus obtained are shown to be electromagnetic in origin as a particular case. It is also shown that the generally used pure charge condition, viz., $ ρ+ p_r = 0 $ is not always required for constructing electromagnetic mass models.15 pages, 3 eps figuresGeneral Relativity and Quantum CosmologyRelativistic anisotropic charged fluid spheres with varying cosmological constanttext
