Abstract
A multiplanar electromagnetic array is disclosed herein, where the array includes a first electromagnetic coil in a first plane, a second electromagnetic coil in a second plane, and a third electromagnetic coil in a third plane. A microactuator is configured to energize electromagnetic coils in the array in sequence, thereby forming a moving electromagnetic field that moves a permanent magnet positioned above the multiplanar electromagnetic array. Movement of the permanent magnet effectuates desired movement of a bead that is in a channel of an immunoassay device.
