A [potentiometer](https://en.wikipedia.org/wiki/Potentiometer) (or pot) is a three-terminal resistor with a sliding or rotating contact that can be used to dynamically vary resistance.

Enter Edwin Hall. As a PhD student at Johns Hopkins in 1879, Hall discovered the "Hall effect", which is the production of a small voltage difference across an electrical conductor **transverse** to the electric current when a magnetic field is applied ([Wikipedia](https://en.wikipedia.org/wiki/Hall_effect#Discovery)). This [animation](https://youtu.be/wpAA3qeOYiI) by "How to Mechatronics" helps demonstrate the effect. When a magnet is introduced, it repels negative charges to one side of the conductor creating an asymmetric distribution of charge (perpendicular to the flow of current) on the conductor. This separation of charge establishes a new electric field with a small electric potential (often in the millivolts), which can be measured by a multimeter or similar device.
