This paper is devoted to study Bianchi type I cosmological model in Brans-Dicke theory with self-interacting potential by using perfect, anisotropic and magnetized anisotropic fluids. We assume that the expansion scalar is proportional to the shear scalar and also take power law ansatz for scalar field. The physical behavior of the resulting models are discussed through different parameters. We conclude that in contrary to the universe model, the anisotropic fluid approaches to isotropy at later times in all cases which is consistent with observational data.
