Bianchi type-I magnetized cosmological models with time-dependent gauge function b for stiff fluid distribution within the framework of Lyra geometry are investigated. To get the deterministic model of the universe, we have assumed that eigenvalue (s11) of shear tensor (sij) is proportional to the expansion (q). This leads to A=(BC)n where A, B and C are metric potentials. The physical and geometrical aspects of the models and singularities in the models are discussed.
