Abstract
A magnetic positioning device includes a magnetic scanning unit and a magnetic sensing unit. The magnetic scanning unit is for forming a first magnetic surface and a second magnetic surface. The first magnetic surface and second magnetic surface rotatably form a detection space. The magnetic sensing unit is disposed in the detection space for recording a first time point and a second time point. The magnetic sensing unit is in contact to the first magnetic surface at the first time point and defines a first-angle data. The magnetic sensing unit is in contact to the second magnetic surface at the second time point and defines a second-angle data. The first-angle data and the second-angle data define a location data of the magnetic sensing unit in the detection space with respect to the magnetic scanning unit, wherein the first time point is not the same as the second time point.
