Esquema explicativo.

霍尔效应Hall effect)是指当固体导体放置在一个磁场内,且有电流通过时,导体内的电荷载子受到洛伦兹力而偏向一边,继而产生电压(霍尔电压)的现像。电压所引致的电场力会平衡洛伦兹力。通过霍尔电压的极性,可证实导体内部的电流是由带有负电荷的粒子(自由电子)之运动所造成。霍尔效应于1879年被埃德温·赫伯特·霍尔(Edwin Herbert Hall)发现。

除导体外,半导体也能产生霍尔效应,而且半导体的霍尔效应要强于导体。

Hall effect 霍尔效应

(重定向自Corbino effect)
Hall effect current sensor with internal integrated circuit amplifier. 8 mm opening. Zero current output voltage is midway between the supply voltages that maintain a 4 to 8 Volt differential. Non-zero current response is proportional to the voltage supplied and is linear to 60 amperes for this particular (25 A) device.

Multiple 'turns' and corresponding transfer function.

The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.
