Coil with Variable Number of Turns per Unit Length for the investigation of magnetic flux density of cylindrical coils as a function of the number of turns per unit length.
The flux density is measured using a teslameter with Hall sensor (e.g. item no. 1024236). An insertable plastic strip is used to mount a compass in order to determine how the field lines align. The coil can be mounted on any 10-mm stand rod.
