Fig. 3. a An original CNT cantilever and the cylindrical magnet nearby. b When the magnet is moved toward the CNT cantilever, the attraction and deflection of the cantilever can be clearly observed and measured. In the inset, the solid and dashed lines not in scale correspond to the cantilever in panels b and a, respectively. c The cut-off CNT cantilever, which is obtained by cutting off the tip of the one shown in panel a, and the cylindrical magnet nearby. d When the magnet is moved toward the CNT cantilever, the attraction and deflection of the CNT cantilever can be clearly observed and measured. In the inset, the solid and dashed lines not in scale correspond to the cantilever in panels d and c, respectively.
