The principle of operation of the sensor of impulses with Hall's converter
And yes In – the operating electrodes,
N – the direction of magnetic field (perpendicular to a surface),
E and F – electrodes between which there is a potential difference (Hall's tension)
If the corresponding semiconductor via which current between electrodes (A) proceeds and (In) is subjected to influence of magnetic field (N), then between electrodes (E) and (F) of this semiconductor there will be a difference of potentials. This phenomenon carries the name of effect of Hall.
