Coulomb drag between two quantum wires is exponentially sensitive to the
mismatch of their electronic densities. The application of a magnetic field can
compensate this mismatch for electrons of opposite spin directions in different
wires. The resulting enhanced momentum transfer leads to the conversion of the
charge current in the active wire to the spin current in the passive wire.
