variable number of turns coil

The Variable Number of Turns Coil investigates the magnetic flux density of cylindrical coils. The number of turns per unit length is determined by the strength of the magnetic field using a teslameter and Hall sensor. A plastic strip allows a compass to be mounted to visually prove how the field lines align. The coil can be mounted on any 10mm stand rod for easy use.
