Description

Предлагаемый прибор дл  демонстрировани  размагничивани  тел при нагревании выполнен в виде ма тника с никелевой чечевицей, между которой и ма тником помещено плам  горелки, подогревающее периодически упом нутую чечевицу в момент приближени  к -магниту, вследствие чего она размагничиваетс  и отходит от магнита.The proposed device for demonstrating the demagnetization of bodies when heated is made in the form of a tiller with nickel lentils, between which and the burner flame is placed, which heats up the periodically mentioned lentils as they approach the α-magnet, as a result of which it is demagnetized and leaves the magnet.

На чертеже фиг. 1 изображает вид собранного прибора в вертикальной плоскости; фиг. 2 - то же, вид сверху.In FIG. 1 shows a view of the assembled instrument in a vertical plane; FIG. 2 - the same, top view.

Устройство предлагаемого прибора в виде магнитного ма тника основано на особенности магнитных металлов; железа , никел  и т. п., заключающейс  в том, что они тер ют свои магнитные свойства при нагревании их до определенной температуры.The device of the proposed device in the form of a magnetic tandem is based on the features of magnetic metals; iron, nickel, etc., in that they lose their magnetic properties when they are heated to a certain temperature.

Как известно, железо тер ет магнитные свойства при температуре красного калени  около 750°-800°, а никель тер ет их при температуре, приблизи тельно, около 300°.Iron is known to lose magnetic properties at a red-hot temperature of about 750 ° -800 °, and nickel loses them at a temperature of about 300 °.

Потер  магнитных свойств происходит при этом с некоторой, определенной известными границами, резкостью. Это значит, что в течение сравнитель (425)Loss of magnetic properties occurs with a certain, defined by known boundaries, sharpness. This means that during a comparator (425)

НО небольшого промежутка времени до критической температуры магнитные свойства железа и никел  еще довольно заметн.ы.BUT for a short time before the critical temperature, the magnetic properties of iron and nickel are still quite noticeable.

Как показано на чертеже, на небольшой дерев нной подстановке устансапен медный штатив с бегунками 1, закрепл ющимис  винтом. Бегунок свободно передвигаетс  по штативу и может быть установлен в нужное положение. К бегунку прикреплена медна  спица, имеюща  прорезь на свободном конце. В прорезь вставлена шпилька, на которой подвешен ма.тник 2, состо щий из медной проволоки 1 мм толщиной и 200 мм длиной. К концу проволоки прикреплен небольшой груз, образующий чечевицу 3 ма тника. Дл  получени  лучших результатов чечевицу хорошо сделать из никел , так как его не приходитс  черезчур долго нагревать: его критическа  температура невысока .As shown in the drawing, a copper tripod with sliders 1 fastened with a screw is mounted on a small wooden substitution. The slider moves freely around the stand and can be set to the desired position. A copper needle is attached to the runner, having a slot at the free end. A pin is inserted in the slot, on which is suspended a m. 2, consisting of copper wire 1 mm thick and 200 mm long. A small load is attached to the end of the wire, forming 3 lentil lentils. For better results, lentils are well made from nickel, since it does not have to be heated too long: its critical temperature is low.

Вес чечевицы и всего ма тника зависит от силы источника тепла. Пользу сь обыквовенной спиртовой лампочкой с диаметром фитильной трубки в 5,5 мм, можно получить хорошлеThe weight of lentils and the whole tartar depends on the strength of the heat source. The use of an ordinary alcohol lamp with a wick tube diameter of 5.5 mm can be obtained well.
