本文所指的亥姆霍茨线圈,实际上就是指用以定丝悬式磁秤的格值线圈。亥姆霍茨线圈由一对大小一样,圈数相等,方向相同,离开一定距离串联的线圈组成。当两线圈间的距离d等于线圈的半径r时,两线圈间的磁场最均匀。东德进口的格值线圈,常数在50r/毫安左右,圈数是7圈(指单个线圈),两线圈间的距离是12.5公分,半径则是12.45。物探仪器修造所出品的,有6圈的,也有8圈的。其他规格和东德进口的相同。线圈常数一般是用一标准的大亥氏线圈比较得来
Helmholtz referred to in this article coil, in fact, refers to the fixed value of the magnetic suspension coil scale value coil. Helmholtz coil by a pair of the same size, the same number of turns, the same direction, leaving a certain distance from the coil in series. When the distance d between the two coils is equal to the radius r of the coil, the magnetic field between the two coils is the most uniform. East Germany imported grid value coil, constant 50r / mA or so, the number of laps is 7 laps (referring to a single coil), the distance between the two coils is 12.5 cm, the radius is 12.45. Geophysical equipment built by the production, there are 6 laps, there are 8 laps. Other specifications and the same imported from East Germany. Coil constants are generally compared with a standard Big Ben’s coil
