1. A magnetic actuator configured to isolate particles in a fluid assay, the magnetic actuator comprising:
a first shielded magnet comprising a first shield coupled to and covering a portion of a first permanent magnet, where the first shielded magnet has a thickness, a length, and a first axis of rotation; a motor coupled to the first shielded magnet and configured to rotate the first shielded magnet about the axis of rotation; and a lateral support member configured to support the first shielded magnet and the motor.
