In accordance with aspects and embodiments, a magnetically driven liquid dispersion device is provided comprising a rotor, a funnel, and a rotary sprayer. The rotor is received by the funnel comprises an Archimedes screw and at least one diametric rotor magnet. The sprayer receives the funnel and comprises at least one diametric sprayer magnet. Application of an external rotating magnetic field generated by, for example, magnetic stirrer, causes the rotor to rotate within the funnel. Rotation of the rotor causes rotation of the sprayer about the funnel.
