Abstract

A device and method for rotating magnetically inducible particles (204) suspended in a fluid by rotating a multidirectional magnetic field through the suspended particles. A rare earth magnet (502) is positioned adjacent to the suspended particles and oriented such that the axis of a magnetic field generated by the magnet passes through the suspension. The magnetic flux lines of the magnet's field radiate in multiple directions through the suspended particles, them to form long multidirectional chains (601). The magnet and the chains of suspended particles (601) are rotated with respect to one another, the axis of the rotation (503) being approximately parallel to the magnetic axis of the multidirectional magnetic field. This causes the particle chains (601) to rotate about the magnetic axis, thus mixing the fluid.
