FIELD: astrophysics. ^ SUBSTANCE: method and device can be used for investigation of deep dynamics of planets. Weight in form of body of rotation is suspended by means of thread on the support mounted for rotation around vertical axis. Weight is submerged into fluid disposed inside vessel which is capable of rotating around the other vertical axis and distance between vertical axes of rotation of support and vessel is preset. Vessel is driven into rotation at permanent angular velocity and supported is rotated synchronously with rotation of the weight. While changing distance between axes of rotation, maximal angular velocity of weight is measured relatively the distance. Influence of solid core's tidal shift is evaluated on velocity of its western drift is evaluated on the base of the dependence found before. The relation of (Omega-omega)/Omega=s/r is used, where r is radius of sphere taken as model of solid core, s is distance between axes of rotation of vessel and core taken as an analog of tidal shift of solid core, Omega is permanent angular velocity of vessel, (Omega-omega)is analog of angular velocity of western drift. According to the other version of the method, vessel and sphere suspended on the thread are both put into rotation with different permanent velocities and distances between their axes of rotation are found at which distances angle of thread twist equals to zero. Device has two pulleys having vertical axes of rotation. Vessel containing fluid is mounted onto lower pulley and sphere is suspended by means of thread on top pulley admitting horizontal movement. Simulation represents western drift of geomagnetic field from where follows that the source of the field has to be solid magnetized envelope of internal core subjected to periodical heating till melting and changing polarity at repeated hardening. Thickness of the envelope is limited by change of phase in FeH at sharp drop of pressure of melting lower than 3000GPa. Raise in frequency of field inversions is caused by deposition of thorium dioxide on the envelope which interrupts once every 100 million years due to convective collapse in external liquid core. Pressure of 300GPa splits d-zone of electrons of envelope to form filled subzone being spin-noncompensated and isolated from Fermi level by energy gap which allows excluding influence of temperature on magnetic order. The phenomenon is called as baromagnetism. ^ EFFECT: improved comfort at exploitation. ^ 23 cl, 55 dwg |
