Elasticity of an Air Cavity in a Magnetic Fluid on an Annular Magnet Segment with Changing Magnetic Field Sign

Аннотация

The paper discusses the results of experimental research on air cavity capture by magnetic fluid and elasticity of the produced oscillatory system on an annular magnet segment with changing magnetic field sign. This research relied on analysis of magnetic and acoustic oscillograms. It was shown that using the magnetic field segment of an annular magnet with this distinctive feature expands the possibilities of managing the magnetic fluid when producing an isolated gas cavity with a reduced value of elasticity parameter.
