Source sentences:
text: The magnetic field does no work, so the kinetic energy and speed of a charged particle in a magnetic field remain constant.
text: The particle’s kinetic energy and speed thus remain constant.
text: The speed and kinetic energy of the particle remain constant, but the direction is altered at each instant by the perpendicular magnetic force.
