#### Abstract

In this study, we first obtained the cosmological term naturally in the Einstein–Hilbert type effect for the $f\left(R,T\right)$ theory, then we discussed the magnetized string matter in the Marder universe, later the matter Lagrangian is not equivalent to string dust and we calculated independently for the string dust and the electromagnetic field, and added the magnetized string together. Finally, we studied the physical and geometric structure of the universe, limiting our results to some astrophysical observation data.
