Abstract

Sensors for outputting signals indicative of a magnetic drag force between a feiTomagnetic sample that is or has been in motion relative to one or more measurement magnets are described. Such sensors include at least one measurement magnet and a sensing element operably associated therewith, such that upon or after exposure of the measurement magnet(s) to a ferromagnetic sample in motion relative thereto, the sensor can sense the drag force, if any, or changes therein, experienced by the measurement magnet. Devices for detecting and/or measuring magnetic drag force that employ one or more of these sensors are also described, as are various applications for such devices.
