In this paper, we have examined the magnetized strange quark matter (MSQM) distribution in the inhomogeneous anisotropic Einstein-Rosen universe model within the framework of f(R,T) theory and General Relativity (GR) in order to investigate whether there was a magnetic field in the first moments of the universe. With the help of the arbitrary F(r) function, we researched for solutions in both theories for various cases. We have seen that the cubic function F(r) = r3 gives meaningful results in both theories. We have obtained magnetic field-free strange quark matter solutions for the quadratic and constant states of the arbitrary function F(r). It is seen that the choice of geometry (selection of the F(r) function) has an effect on the presence of the magnetic field. Finally, the physical results are examined on 3D graph.
