This application describes creating, modifying, and bending electromagnetic solitons at large scales for the various applications. An electromagnetic soliton generator system controls the magnetic soliton such that the orientation, rotation rate, pitch angle, and magnetic field strength of the solitons are modified to provide the described standing waves and generate a magnetic flux differential.

A multipole electromagnet for injecting particles, including a hollow duct extending along a longitudinal axis, and a plurality of wire conductors that are placed parallel or substantially parallel to the longitudinal axis along the duct, electrically connected in series and arranged to conduct electric current. The directions of the electric current flowing through the wire conductors are symmetric about a first plane of symmetry. The wire conductors are distributed in multiple carrier planes that are parallel or substantially parallel to the first plane of symmetry, including two main carrier planes that are symmetric about the first plane of symmetry and located outside the hollow, each main carrier plane carrying wire conductors that conduct the electric current in the first direction and wire conductors that conduct the electric current in the second direction opposite the first direction.

The present invention discloses propulsion system operating exclusively in electromagnetic domain. Only electromagnetic field and direct electric current are used to generate propulsion force. In exemplary embodiment two switchable electromagnets, one to generate electromagnetic field, the other to generate electromagnetic force are used. To disable electromagnetic reaction force on electromagnetic field generator, streams of independent but synchronized direct current pulses passing through two electromagnets are organized in the way that first electromagnet is always carrying current when magnetic field generated by second electromagnet reaches it, thus generating Laplace force, whereas, second electromagnet is never carrying current (open circuit) when magnetic field generated by the first electromagnet reaches it, which means, no Laplace reaction force ever occurs on second electromagnet. The system therefore does not depend on the emission of matter. Only electric current is needed.

A device for applying a constant magnetic field to a volume of interest (VOI) has been developed. At least one magnetic field source and a permeable yoke, which guides the magnetic flux generated by this magnetic field source into the volume of interest (VOI). The yoke is guided through at least one closed conductor loop, which can be switched to the superconducting state so that, in the superconducting state of the conductor loop, a change in the flux through the yoke effects a current counteracting this change along the conductor loop. It has been identified that, in this way, the stabilizer for the magnetic field can be spaced so far apart from the volume of interest (VOI) that the field distribution in this volume is virtually no longer influenced. At the same time, the quality of the stabilization is also improved, since the conductor loop is no longer exposed to the entire magnetic field prevailing in the volume of interest (VOI). The entire critical current that the conductor loop can carry is available as a control range for compensating for fluctuations in the flux. In comparison with the prior art, the invention first accepts the apparent disadvantage that, in general, additional means are required for switching the conductor loop back and forth between the superconducting state and the normal-conducting state. However, this disadvantage is more than compensated for.

An improved long range coil and driver assembly for a magnetic field generator wherein the driver and coil generate a large magnetic field is provided. The coil and driver assembly includes a source impedance control network which includes a plurality of pairs of resistors and amorphous noise suppression devices, and a coil that utilizes a unique basket weave winding pattern to reduce the effect of the back EMF from one wire on the adjoining wires, thereby reducing the impedance of the coil. The reduced impedance and improved impedance control increases the current that can flow creating a larger field.

The present invention discloses an electric field propulsion system for spacecraft. The system includes a capacitor stack comprising an array of supercapacitors. Solid-state electronic circuits generate modulated currents and electric fields in pulse coils. The pulse coils direct the electric fields onto separated electric charges stored in the capacitor stack. The resulting unidirectional Lorentz Forces thereby generate thrust without reaction mass. Reaction momentum is carried away by Poynting Vector fields in conformity with the currently understood principles of electrodynamics. The design is scalable down to micro-chip sized thrusters.

A magnetic trap is configured to arrange at least one diamagnetic rod. The magnetic trap includes first and second magnets on a substrate that forms the magnetic trap defining a template configured to self-assemble diamagnetic material. Each of the first and second magnets extends along a longitudinal direction to define a magnet length, and contact each other to define a contact line. The first magnet and the second magnet have a diametric magnetization in a direction perpendicular to the contact line and the longitudinal direction so as to generate a longitudinal energy potential that traps the diamagnetic rod along the longitudinal direction.

A ferrofluid chamber has a housing that is adapted to be coupled to a component that generates a magnetic field. The housing may be disposed around the component so as to insulate a noise-producing region of the component. The magnetic field may be of sufficient strength to stimulate anatomical tissue. In addition, a ferrofluid may be disposed within the housing for cooling the component.
