Description
через центр генераторной катушки перпендикул рно ее оси, и намотаны на каркас 5 из немагнитного и непровод щего материала .through the center of the generator coil perpendicular to its axis, and wound on a frame 5 of non-magnetic and non-conductive material.
На фиг, 1 длина генераторной катушки обозначена , ее средний диаметр « , средний диаметр приемной катушки - D , рассто ние между обмотками приемной катушки - Н. Обмотки 3, 4 приемной катушки включены последовательно и встречноIn FIG. 1, the length of the generating coil is indicated, its average diameter, the average diameter of the receiving coil is D, the distance between the windings of the receiving coil is N. Winding 3, 4 of the receiving coil are connected in series and counter
(фиг. 2). Генераторна катушка 1 иодклю- чена к генератору синусоидального напр жени низкой частоты, с обмоток 3 и 4 приемной катушки сигнал поступает на измерительную схекту.(Fig. 2). The generator coil 1 is connected to the generator of a sinusoidal low-frequency voltage, the signal from the windings 3 and 4 of the receiving coil is fed to the measuring circuit.
Работает устройство следуюшим образом .The device works as follows.
Генераторна катушка 1 создает в окружаюшем гфостранстве переменное магнитное поле. В воздухе при отсутствии магнитной среды это поле индуцирует в двух одинаковых встречно включенных обмотках 3 и 4 приемной катушки одинаковые по амплитуде, но противоположные по фазе э, д. с., которые взаимно компенсируют друг друга. На выводах приемной катушки наблюдаетс нулева з.д.с.The generator coil 1 creates an alternating magnetic field in the surrounding space. In the air, in the absence of a magnetic medium, this field induces in two identical oppositely connected windings 3 and 4 of the receiving coil of the same amplitude, but opposite in phase e, dc, which mutually compensate each other. At the terminals of the receiving coil, zero wc is observed.
Над магнитной средой устройство располагаетс так, чтобы совмешенные оси катушек были перпенд,икул рны ее поверхности . Полем генер торной катушки среда намагмичлваетсй, -следствие чего по вл е4Above the magnetic medium, the device is positioned so that the combined axes of the coils are perpendicular and well curved of its surface. The field of the generator coil is magnetized by the medium, resulting in 4
с вторичное магнитное поле. Поскольку обмотки приемной катушки располагаютс на различном рассто нии до поверхности среды, в них индуцируютс различные по величине вторичные э,д.с. На выводах приемной катушки по вл етс вторична э.д.с по величине которой определ етс магнитна восприимчивость.with secondary magnetic field. Since the windings of the receiving coil are located at different distances to the surface of the medium, they are induced in various secondary e, s. At the terminals of the receiving coil, a secondary emf appears, the magnitude of which determines the magnetic susceptibility.
Величина разностной э.д.с. приемной катушки, благодар соосному расположению не измен етс при повороте устройства вокруг совмешенных осей катушек даже над неоднородной средой.The magnitude of the differential emf the receiving coil, due to the coaxial arrangement, does not change when the device is rotated around the combined axes of the coils, even over a heterogeneous medium.
