Theory of Hall sensor: When a current IS flows
through a semi-conductor chip, one Hall voltage is
generated in the right-hand direction of the
current, of which the voltage UH is in proportion
to the magnetic field induction B (perpendicular to
the current IS) and the current IS. The Hall voltage
is subject to the varying magnetic field induction
strength B.
