Description
Изобретение относитс к области измерительной техники и геофизики и в частности касаетс устройств дл создани однородного магнитного пол .The invention relates to the field of measurement technology and geophysics, and in particular, to devices for creating a uniform magnetic field.
Известны устройства дл создани однородных магнитных полей, в которых применена система из двух квадратных плоских катушек разных размеров, включенных согласно в цепь намагничивающего посто нного тока.Devices are known for creating uniform magnetic fields in which a system of two square flat coils of different sizes is used, connected according to a magnetizing direct current circuit.
Предлагаемое изобретение имеет цель повысить однородность создаваемого катушками магнитного пол . Отличительной особенностью изобретени вл етс включение катушек в цепь намагничивающего тока таким образом, чтобы создаваемые ими магнитные пол были направлень встречно.The present invention aims to improve the uniformity of the magnetic field generated by the coils. A distinctive feature of the invention is the inclusion of coils in the magnetizing current circuit in such a way that the magnetic fields created by them are directed oppositely.
На чертеже изображено предлагаемое устройство.The drawing shows the proposed device.
Две квадратные обмотки по Wo витков кажда , со стороной квадрата bo, отсто щие друг от друга на рассто нии С„ 0,5445 bo и соединенные последовательно, образуют основную плоскую катушку, создающую поле HO. Добавочна пара также последовательно соединенных квадратных обмоток, имеющих по Wg витков кажда , со стороной квадрата bf, , образует добавочную плоскую катущку, расположенную внутри основной катушки. Добавочна катущка создает поле Hg. Основна и добавочна катущка включены в цепь посто нного тока так, что создаваемые и.ми магнитные пол Но и Hg имеют противоположное направление. Встречное направление магнитных полей обеспечивает повышение однородности результируюшего магнитного пол .Two square windings along the Wo turns each, with the side of the square bo, spaced from each other at a distance C = 0.5445 bo and connected in series, form the main flat coil creating the HO field. An additional pair, also of series-connected square windings, each having Wg turns, with a side of square bf,, forms an additional flat coil located inside the main coil. The additional roller creates the Hg field. The main and additional coils are included in the DC circuit so that the magnetic fields Ho and Hg generated by these themselves have the opposite direction. The opposite direction of the magnetic fields increases the homogeneity of the resulting magnetic field.
№ 141940 Предмет изобретени № 141940 The subject invention
Устройство создани однородного магнитного пол , содержащее две параллельно расположенных плоских квадратных катушки разных размеров,центры которых наход тс на одной пр мой, отличающеес тем, что, с целью повышени однородности создавае1 1ого катущками результирующего магнитного пол , катушки включены в цепь намагничивающего тока таким образом, чтобы создаваемые ими магнитные пол были напоавлены встпечно.A device for creating a uniform magnetic field containing two parallel-arranged flat square coils of different sizes, the centers of which are on the same straight line, characterized in that, in order to increase the uniformity of the coils resulting in the magnetic field, the coils are included in the magnetizing current circuit so that the magnetic fields created by them were added to each other.
