    • An apparatus to pump fluids comprises an annular bore and at least one pair of magnetic pistons which travel along the bore. The one piston is moved along the bore by progressively shifting electromagnetic fields to be the traveling piston while the other piston is locked in place between the inlet and outlet ports to become the stationary piston. The traveling piston draws fluid into the apparatus while pushing fluid out. As the traveling piston approaches the rear of the stationary piston, a changeover occurs where the traveling piston becomes locked to the bore to become the stationary piston and the stationary piston becomes released from the bore to become the traveling piston. This arrangement is continuously repeated to provide a pump/compressor/electric motor/ and the like.
