I think it's the force needed to keep the wire moving relative to the magnet, not the magnetic force itself, that does the work that creates current in the wire.
Magnetic part of the Lorentz force F on a change Q moving with a velocity vector V in a magnetic field B
F=kQ V x B is perpendicular to the velocity V.
A force that is perpendicular to the velocity of a particle, does not do work (thus, cannot change its speed). How then it possible to create electric current by moving a metal wire in magnetic field?
