1. Способ контроля физико-механических свойств магнитной жидкости посредством смещения и колебания ее в столбике в магнитном поле, заключающийся в удержании магнитным полем в прозрачной полости столбика магнитной жидкости, сообщающейся с U-образной полостью, заполненной дистиллированной водой, и последующей фиксации колебаний посредством индикатора вибрации в виде катушки индуктивности с передачей сигнала через усилитель на осциллограф, и смещение ее контроля уровня дистиллированной воды в U-образной полости. 1. A method of controlling the physicomechanical properties of a magnetic fluid by displacing and oscillating it in a column in a magnetic field, which consists in holding a magnetic field in a transparent cavity of a column of magnetic fluid in communication with a U-shaped cavity filled with distilled water, and then fixing the vibrations with an indicator vibration in the form of an inductor with the transmission of a signal through an amplifier to an oscilloscope, and the shift of its control of the level of distilled water in a U-shaped cavity. 2. Устройство для выполнения способа, содержащее полость с патрубками входа и выхода магнитной жидкости, и удерживаемой в магнитном поле кольцевого магнита, отличающееся тем, что полость с магнитной жидкостью выполнена из прозрачной трубки, расположенной горизонтально и параллельно поверхности полюсного зазора кольцевого магнита с изменяющимся магнитным полем, а выход прозрачной трубки соединен посредством силиконовой трубки с полостью, выполненной в виде U-образной трубки, которая заполнена дистиллированной водой.2. A device for performing the method, comprising a cavity with magnetic fluid inlet and outlet nozzles and held in a magnetic field of a ring magnet, characterized in that the cavity with magnetic fluid is made of a transparent tube located horizontally and parallel to the surface of the pole gap of the ring magnet with a changing magnetic field, and the output of the transparent tube is connected via a silicone tube to a cavity made in the form of a U-shaped tube, which is filled with distilled water. 3. Устройство по п.2, отличающееся тем, что полость из прозрачной трубки выполнена с поршнем для возбуждения колебаний, который соединен с патрубком ее выхода, а в зазоре между прозрачной трубкой и поверхностным наконечником кольцевого магнита на уровне свободной поверхности магнитной жидкости установлен индикатор в виде катушки индуктивности. 3. The device according to claim 2, characterized in that the cavity of the transparent tube is made with a piston for exciting vibrations, which is connected to the outlet pipe, and an indicator is installed in the gap between the transparent tube and the surface tip of the ring magnet at the free surface of the magnetic fluid inductance coil.
