Since the magnetic force on a moving charged particle is qv X B, the work done by a static magnetic field is always zero.
The magnetic field itself does no work on the moving charges, it merely deflects them. This deflection induces an electric field in the wires, which acts on the wire's positively charged lattice, and does the work in moving the wires together.
