霍尔效应是磁电效应的一种,是美国物理学家霍尔(A.H.Hall)于1879年在研究金属的导电机构时发现的.当电流垂直于外磁场通过导体时,在导体的垂直于磁场和电流方向的两个端面之间会出现电势差,这一现象便是霍尔效应,这个电势差叫做霍尔电
Hall effect is a kind of magnetoelectric effect, which was discovered by American physicist AH Hall in 1879 when studying the conduction mechanism of metal.When the current is perpendicular to the external magnetic field passing through the conductor, Potential difference between the two end faces of the magnetic field and current direction, this phenomenon is the Hall effect, this potential difference is called Hall electricity
