Description

разуюилх замкнутую электрическу1с цепь с KaTyfflKaNi 2 i, 3 солеио ща, при этом пара снхо-.етричных катушет; включены последузателькл, а все пары - параллельно .Razuiloh closed electric circuit with KaTyfflKaNi 2 i, 3 soliio, with a pair of sno-electric coils; followed by a switch, and all pairs - in parallel.

Устройство работает следующим образом ,The device works as follows

С помощью комм}-татора 8 катушки соленоида все или отдельными парами подключаютс  к источн -ису питани  7 Ток через катушки выставл етс  с помощью реостата 6 и контролируетс  по амперметру 5 При этом напр женность пол  в области, занимаемой кюветой 4, равна сумме напр женностей , создаваемык каждой из симметричны к пар катущек 2 и 3, Так как дл  любой пары катущек поле в области кюветы однородно, то и суммарное поле будет однородным. Кроме того, параллельное включение всех пар катущек значительно уменьшает индуктивность соленоида, а следовательно упрощает процессы коммутаиии и требуемого дл  измерени  измеиегги  величины тока.Using a comm} -tator 8, the coil of the solenoid is connected to the power supply source 7 all or in separate pairs. The current through the coils is exposed by means of a rheostat 6 and monitored by an ammeter 5. The field voltage in the area occupied by the cell 4 is equal to the sum of the voltages , created each of the symmetric to the pairs of the coils 2 and 3, Since for any pair of coils the field in the region of the cuvette is uniform, then the total field will be uniform. In addition, the parallel connection of all pairs of coils significantly reduces the inductance of the solenoid, and therefore simplifies the switching processes and the amount of current required to measure the change.
