Work and a magnetic field

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?
