A family of stationary solutions for magnetically driven outflows has been discovered by time-dependent, axisymmetric magnetohydrodynamic simulations of outflows from an accretion disk threaded by an inclined magnetic field. At the disk surface matter was given a small initial push with a speed less than the slow magnetosonic speed. In the simulations, the outflowing matter is observed to be accelerated by magnetic force and by centrifugal force up to velocities in excess of the fast magnetosonic speed and in excess of the escape speed from the central object.
