摘要

提出了一种同轴电缆结构的霍尔效应装置.若中心导体通电流,则在通电的导体壳内外表面之间产生霍尔电势差.

讨论了导体壳电势差与中心导体的电流强度、导体壳的电流强度以及导体壳结构之间的关系,发现导体壳很薄时霍尔电势差

最大.

Abstract

A Hall effect device with coaxial cable structure is proposed. When the central conductor passes

through the current,the potential difference between the inside and outside surfaces of the conductor shell through

current is generated. We discuss the dependence of the potential difference on the currents through the central

conductor and the conductor shell and the sizes of the conductor shell,and find that the maximum value of the Hall

potential difference appears as the conductor shell is very thin.
