Hall effect of elevator handrail manufacturers



The Hall coefficient measured by the Hall effect experiment can judge important parameters such as the conductivity type, carrier concentration, and carrier mobility of semiconductor materials. The Hall voltage changes with the strength of the magnetic field. The stronger the magnetic field, the higher the voltage, the weaker the magnetic field, and the lower the voltage. The Hall voltage is very small, usually only a few millivolts, but amplified by the amplifier in the integrated circuit. This voltage can be amplified enough to output a stronger signal.
