Design and instrumentation of a magnetic field micro-probe mapper: An e-lab aparatus to map a coil's magnetic field

The magnetic field experimental study is a difficult task as quantitative magnetic experiments are not so common in schools mostly due to the necessary instruments sensitiveness. In this experiment we devise an apparatus capable of tracing the local 3-D magnetic field vector components. The main objective of this device is to allow the understanding of the field's magnetic vector nature and letting the student distinguish between field lines and contour lines of equal magnitude.
