could a particle accelerator be built in which all the forces on the particle, for steering and for increasing speed are magnetic forces?

A magnetic field that is stationary can only provide a force perpendicular to the motion of the particle. Which will not cause it to gain speed.
A CHANGING magnetic field creates an ELECTRIC FIELD which can and does accelerate the particle.
But is it the magnetic field or is it the electric field which does the work?
So you can build a particle accelerator that uses ONLY electromagnets to do the powering.
Yet the FORCES on the particle are not entirely magnetic forces. There must be an electric field to do the accelerating.
