1. A magnetic actuator configured to isolate particles in a fluid assay, the magnetic actuator comprising:
a first magnet magnetized in a first direction, a second magnet magnetized in a second direction, a third magnet magnetized in a third direction, and a fourth magnet magnetized in a fourth direction, wherein the directions are not identical and each direction is either parallel or orthogonal to the other directions such that a Halbach effect is induced on one side of the magnets; a motor configured to rotate at least two of the first, second, third and fourth magnets; and a lateral support member configured to support the motor, the first magnet, the second magnet, the third magnet, and the fourth magnet. |
