In this paper, we present a different technique for investigating spherical [Formula: see text]-microfluidic optical mKdV electromotive [Formula: see text] forces in [Formula: see text] Then, we give some relations for ferromagnetic spherical [Formula: see text]-microfluidic optical mKdV magnetic [Formula: see text] flux density. Ferromagnetic spherical [Formula: see text]-microfluidic optical mKdV magnetic [Formula: see text] flux surface model. Finally, we obtain spherical [Formula: see text]-microfluidic optical mKdV magnetic [Formula: see text] flux density.
