The possibility is examined that angular momentum is removed magnetically from an accretion disk by field lines that leave the disk surface, and is eventually carried off in a jet moving perpendicular to the disk. The mechanism is illustrated by a self-similar MHD solution, with the gas being regarded as cold and starting from rest at the equatorial plane, with the disk itself in Keplerian orbit about a black hole. It is shown that a centrifugally driven outflow of matter from the disk is possible if the poloidal component of the magnetic field makes an angle of less than 60 deg with disk surface. At large distances the outflow forms a pair of collimated, antiparallel jets, while close to the disk it is probably driven by gas pressure in a hot, magnetically dominated corona.
