Li++ Force on a moving charged particle, F = qVBsin $\theta$ ​As velocity V and magnetic field B are constant, and angle between the magnetic field and charged particle is $90^\circ$ , the only thing on which force F depends is charge q. Now, the charge on Li++ charge on electron, proton or He+ . So the force is maximum for Li++.
