In this context, we pay our attention to the skyrmion Hall effect of a skyrmion in a nanotube when it is driven by a rotating magnetic field. By using micromagnetic simulations, we study the motion of a skyrmion driven by a rotating magnetic field in a nanotube. We find that the skyrmion moves parallel to the nanotube axis besides rotating around the nanotube, which is due to the skyrmion Hall effect. Both the core polarity of skyrmion and the rotation direction of magnetic field determine the orientation of the skyrmion motion along the nanotube axis. The strength of the skyrmion Hall effect is related to the size of the nanotube, the frequency of the rotating magnetic field and the Gilbert damping coefficient. And the damping coefficient is the only factor that affects the size of skyrmion Hall angle. We also demonstrate that nanotube model has an amplification effect on the skyrmion Hall effect compared with the plane model.
