Definitions

  • the present invention relates to the field of influencing magnetic fields. It relates to a method for influencing the magnetic coupling between two spaced-apart bodies according to the preamble of claim 1 and an apparatus for carrying out the method
  • Diamagnetism is defined as the property of a substance to push out a magnetic field passing through it more or less strongly from its interior or to weaken the magnetic field.
  • An ideal diamagnet is a superconductor of the first kind, which pushes the magnetic field completely out of its interior except for a narrow edge area.
  • circular flows are induced by the external magnetic field according to the model presentation at the atomic level, whose magnetic field is opposite to the external magnetic field and weakens it.
  • a loss-free shielding current is triggered by the external magnetic field in a macroscopic dimension in the edge region, whose magnetic field makes the interior of the SL field-free.
  • a controllable field displacement device having a field displacement region is brought between the two bodies, and that the magnetic field prevailing between the two bodies is displaced in a predetermined manner from the field displacement region of the field displacement device by a corresponding activation of the field displacement device.
  • One way of controlling is to turn the field displacement device on or off to affect the magnetic coupling between the two bodies. This alternates between full field displacement and missing field displacement, which corresponds to a switching process in the magnetic coupling.
  • the field displacement device can be periodically switched on and off to influence the magnetic coupling between the two bodies. But it is also conceivable to change the field displacement device for influencing the magnetic coupling between the two bodies in the strength of the field displacement in order to achieve a continuous change, as is the case, for example, in sinusoidal processes.
  • At least one self-contained Törüidalspuie is used.
  • the Vekiorporeniiai can be influenced by a current flowing through the at least one Toroidalspule in the direction of the axis of the Toroidalspule current-carrying coil.

  • at least one of the bodies may be a permanent magnet whose magnetic field interacts with another body.
  • both bodies can be permanent magnets that attract or repel each other as part of their interaction depending on the polarity.
  • At least one of the bodies may also be an electromagnetic coil which either itself flows through the current and generates a magnetic field or is traversed as an induction coil by a changing magnetic field.
  • both bodies can be electromagnetic coils.
  • a control is used to control the field displacement device.
  • An embodiment of the field displacement device according to the invention is characterized in that the field displacement device comprises at least one toroidal coil whose inner magnetic field is closed annularly and whose outer magnetic field disappears.
  • the field displacement device comprises at least one toroidal coil whose inner magnetic field is closed annularly and whose outer magnetic field disappears.
  • an in-line tion of the axis of the toroidal coil extending current-loadable winding (31) may be arranged.
  • a plurality of toroidal coils are arranged concentrically with one another in a plane directly adjacent to one another.
  • the Toroidalspulen or the winding ind thereby preferably connected to a power supply, which in turn is controlled by a controller.

  • FIG. 2 shows the section through a toroidal coil, as it is part of a field displacement device according to an embodiment of the invention.
  • 3 shows in cross-section an embodiment of the inventive field displacement device with alternately operated concentric Toroidalspulen in two superimposed planes.
  • FIG. 4 shows an illustration comparable to FIG. 1 of an arrangement in which the coupling between a permanent magnet and an electromagnetic coil is influenced according to the invention
  • FIG. 5 shows a representation comparable to FIG. 4 of an arrangement in which the coupling between two electromagnetic coils is influenced according to the invention.
  • FIG. 6 shows a section through a field displacement device according to another embodiment of the invention with a toroidal coil and an additional winding surrounding it for controlling the vector potential.
  • the patent relates to the way in which phenomena and effects of diamagnetism can be produced in a fixed area of space (field displacement area) and how, with the aid of this diamagnetic space area (field displacement area) generated by external currents, an interaction with constant or temporal variable magnetic or electromagnetic fields that can reach into this area from various external independent sources (eg external permanent magnets or electromagnets) can be brought about.

  • gradeA r , D the radial gradient
  • a circular-shaped solenoid (toroidal coil) supplied from a power source may be used, which generates a circular self-contained electromagnetic field B 0 (the direction of the field B D is along the axis of the circular solenoid).
  • B 0 the direction of the field B D is along the axis of the circular solenoid.

  • dA D / dt 0th
  • f (v) function of the frequency of the alternating current
  • KD correction coefficient that takes into account the wave manifestations of AD.
  • Fig. 1 is a simplified view of the principle of the invention
  • the method is based on two bodies 10 and 1 2, which are spaced apart from one another and which are here designed, for example, as permanent magnets and which are magnetically coupled that between them there is an area with a non-zero magnetic flux density of induction 1 1.
