It is shown experimentally for the first time that it is possible to steer charged-particle trajectories by using a curved single crystal. 8.4-GeV protons, which were captured during plane channeling by a curved silicon single crystal, were deflected at an angle of 26 mrad. The radius of curvature of the particle trajectory was about 38 cm, which corresponds to the average transverse electric field of about 240 MV/cm acting on the particle. This is equivalent to a magnetic field with the induction of about 0.82 MG.
