Hall Effect, Magnetic Forces on Moving Charges
The Hall effect manifests itself as a voltage instead of a mechanical force. This makes it suitable as a compact way to measure magnetic fields by directly converting them to a voltage. We already know how to accurately measure voltages, and we can then apply the same technique to measure a magnetic field.
This video also moves on to our next topic, which is also related to the general idea of how magnetic fields deflect moving charges.
