The criteria in the examples of dynamic levitation applied to the physical reproduction of an object orbiting a virtual gravitational mass derived from the Earth's gravity or magnetic objects.All problems related to Earth's gravity must be countered in order to get as close as possible to the conditions of outer space (no friction between the satellite and anything else). To achieve this, magnetic levitation is practically unavoidable. As for friction with the air, the energy required to maintain the satellite's rotation on the orbit it has chosen , its zero friction coefficient zone, must therefore be maintained in rotation by a satellite request servo control device (a device that must cancel out its own friction losses; the drag experienced by the magnet must also be compensated for, as it introduces an electrical error. (this is not an electrical set point parameter for a given speed) 1] Elimination of possible magnetic interference between the levitation geometry and the orbital behavior of the satellite. [2] The visual aspect of the behavior of an object moving in orbit will be enhanced by the addition of a total screen between the object in orbit and the entire system. Note: The choice of “bottom” suspension complicates the design but is necessary to facilitate observation. Geometry No. 5-6©The magnet/object levitating in the “zero friction zone” under the influence of a constant acceleration force g=0.684 ms/s created by the 4-degree slope directed towards the center of rotation, points in real time on the graduated ruler to the radius of the orbit, the result of the experiment.Each orbit corresponds to an “ideal” speed. The system detects the error and refines the speed to maintain the precedent chosen orbit and the energy corresponding to it. Orbiting or changing orbit can be achieved using a very weak external magnetic field of the appropriate polarity, such as a Ø19x19 mm ceramic magnet, passed quickly by hand. As the magnet in levitation passes, it will correct is orbit according to the polarities. The sensitivity of the system is astonishing given the rotating mass (830g), i.e.. “blowing on the counterweight as it passes, is enough to change the orbit.” First video:The observer is outside the system. 1,5 Mo (.avi)This tool permits to reproduce only some aspects of a real orbital movement around an aster : not the inverse square law, not a complete elliptical orbit, not a real central attractive mass, etc., for now it should be viewed only as the equivalent case of the adequate inclination angle given to rails tracks and roads in curves. This model, is the case of a vehicle taking a curve on an icy road, inclined at 4 degrees inside of its circled trajectory, a very precise speed allows it to remain in the center of its lane, regardless of its mass. Second video:Same as the first video but now, the observer is inside the system. 5 Mo (.avi) Next step: modification of the zero friction zone, to apply to (g) the law of "inverse square of the distance".
