When a charged particle moves in an electric field, the field performs work on the particle....

When a charged particle moves in an electric field, the field performs work on the particle. Thus, the energy of the field decreases, turning into kinetic energy of the particle. Does the magnetic field of a permanent magnetic similarly lose energy and perform work when moving a conductor with a current?
