We report trapping and manipulation of permanent magnet microparticles in three dimensions (3-D) by employing a micro-ring actuator to parametrically excite the particles. The actuator is combined with a force sensor to infer the position of a trapped particle along the axis of the ring. We demonstrate experimental results of both trapping and position measurement. The trapped particle has been moved under occluding features and in a variety of trajectories and found to track the center of the micro-ring in all cases. The particle is shown to obey Hill's equation with damping, and the regions of stability in the parameter space of the equation are numerically investigated.
