摘要
介绍了一种可获取线性磁场的装置。该装置由两匝数及半径相同的环形线圈组成,相向平行同轴放置,两线圈之间的距离等于线圈半径,通以大小相同,方向相反的电流,可获得磁感应强度与其线圈中心轴线位置成线性关系的区域。此装置不仅具有独创性,更有实时性及可调的优点,可将其拓展到实际应用,尤其是传感领域,有重要的应用前景和经济价值。
A linear magnetic field obtaining equipment is introduced in this article. In order to seek for the linear range of the equipment,consisting of two parallel and coaxial annular coils with the same number of turns and radius in a distance of the value of the radius,we provide same current intensity with adverse direction for the two coils. Not only does this equipment possess ingenuity and originality,but also it has the advantage of instantaneity and adjustability. It can also be expanded to practical application,such as sensor area,of great economical value and application prospect.
