We investigate the influence of a constant magnetic field on the screening length of a heavy quarkonium propagating through a strongly coupled super Yang–Mills plasma. Our analysis is conducted by evaluating the Wilson loop in a boosted magnetic brane background, with additional consideration of quarkonia axes aligned along different directions. We find that the presence of a magnetic field reduces the screening length, which in turn lowers the quarkonium binding energy. Moreover, the inclusion of a magnetic field enhances quarkonium dissociation, a result that is consistent with prior observations regarding the entropic force and imaginary potential.
