Description
как мешает магнитное поле от подвод щих про .водов. Если установку дл создани внешнего пол вьшол11ить в виде двух параллельных проводников , расположенных в плоскости, проход щей 4ejpe3 ось экрана, то помехи от подвод щих проводов существенно уменьшаютс . При этом ток по проводшкам пропускаетс во взаимно противоположных направлени х.how the magnetic field from the supply wires interferes. If the installation to create an external field is wired in the form of two parallel conductors located in the plane passing the 4ejpe3 axis of the screen, then the interference from the supply wires is significantly reduced. In this case, the current through the conductors is passed in mutually opposite directions.
АтлогИчные сображени применимы дл сферического экрана, коэффициент экранировани которого дл однородного пол совпадает с коэффициентом экранировани в центре экрана дл пр молинейного проводника.The similar examples are applicable for a spherical shield, the shielding coefficient of which for a uniform field coincides with the shielding factor in the center of the shield for a straight conductor.
Таким образом, предлагаемое устройство дл измерени коэффициента экранировани магнитногр экрана с помощью пропускани посто нного тока по пр молинейному проводнику применимоThus, the proposed device for measuring the shielding coefficient of a magnetic screen by passing a direct current along a straight conductor is applicable.
дл магнитных экранов независимо от их размеров .for magnetic screens regardless of their size.
