velocity yes - because there is a directional component, speed no

A magnetic field can change the velocity of a charge which is travelling perpendicular to it by changing its direction of motion (providing a centripetal force) but it doesn't change speed, therefore no change in kinetic energy and no work done.

basically W=Fxd
If the charged particle is moving then the magnetic field will change the velocity of the particle. That requires force. For what distance is the force applied. d = V x (delta t) assumind the velocity does not change. I would say that there is work done.

Wait a second. We are dealing with vectors. The vectors of F and d are perpendicular so that the dot product makes W always equals 0.
