Principio del producto

Es como una carretera. Originalmente, todos se distribuían uniformemente en la carretera y se movieron hacia adelante. Cuando hay un campo magnético, se puede empujar a la gente hacia el lado derecho de la carretera. En ambos lados del circuito antiguo (conductor), habrá una diferencia de voltaje, que se llama “Efecto Hall”. El dispositivo Hall hecho de acuerdo con el efecto Hall es utilizar el campo magnético como medio de trabajo para convertir la salida de movimiento del objeto en la salida en forma de voltaje digital,. Para que tenga las funciones de detección y cambio.

Efecto Hall

Si se aplica una corriente al conductor de un campo magnético seco, la dirección del campo magnético es perpendicular a la dirección del voltaje aplicado, luego se generará otro voltaje en la dirección perpendicular tanto al campo magnético como a la dirección de la corriente aplicada, Y la gente se refiere a esto, el voltaje se llama voltaje Hall, y este fenómeno se llama efecto Hall.
