This invention is a process to modify weather patterns with electromagnetic systems, by creating and/or limiting eddy currents. Oceanwater's salinity increases its electrical conductivity. The conflict between the Earth's electromagnetic field, and the Coriolis Force, is a factor in cyclogenesis. This invented process utilizes artificially induced electromagnetic eddy currents to generate precipitation systems from Eastward Ocean Currents, as well as limits electromagnetic induction caused by the Earth's electromagnetic field, to stall cyclogenesis.

A magnetic field concentrating or guiding device can include one or more coils, and one or more foil, tape and/or bulk superconductor structures disposed in one or more predetermined positions with relation to the coils. The one or more superconductor structures can form one or more magnetic field carrying regions. During operation, current passing through the one or more coils can generate one or more magnetic fields that are compressed or guided in the magnetic field carrying regions.

A magnetohydrodynamic (MHD) flow control mechanism is described which substantially improves the existing processes in that smaller magnetic fields, requiring far less mass, are placed away from the forebody of the spacecraft to produce Lorentz forces that augment the lift and the drag forces for guidance, navigation, and control of the spacecraft.

A tri-axial magnetic field correction coil includes a first coil group and a second coil group with respect to an X-axis direction that passes through a clock transition space in which atoms are disposed. The first coil group is a Helmholtz-type coil composed in a point-symmetrical shape around the clock transition space. The second coil group is composed in a point-symmetrical shape around the clock transition space with respect to the X-axis direction, and is a non-Helmholtz-type coil that differs from the first coil group in terms of coil size, coil shape, or distance between coils.

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.

Accordingly, the vehicle can improve the degree of freedom in design in a vehicle compartment while providing a passenger's convenience by implementing a seat movement mechanism suitable for the era of autonomous traveling.

The present disclosure provides a stellarator magnet based on cubic permanent magnet blocks and an arrangement optimization method thereof. For the characteristic that a three-dimensional magnet coil of a stellarator is complex in structure, the present disclosure provides the stellarator magnet based on the cubic permanent magnet blocks with uniform magnetization, same magnetization and same size; the magnetization directions of the cubic permanent magnet blocks are defined in a limited number of fixed alternative directions; the magnetic field configuration of the stellarator is generated by dipole magnetic fields provided by the permanent magnet blocks and planar coils, so that the device complexity of the stellarator is reduced, and the difficulty and cost of the machining and installation of the magnet are reduced. The shape of the permanent magnet blocks can be replaced by other regular shapes, and the permanent magnet is still formed by the permanent magnet blocks with same shape, same size, uniform magnetization and same magnetization. For the magnet, the present disclosure provides a magnet arrangement optimization method of ‘local compensation’ and related optimization strategies of ‘threshold truncation,’ ‘global fine tuning,’ etc., for meeting different optimization requirements on accuracy of the magnetic fields, usage qualities of magnets, etc., and a magnetic field meeting designing requirements can be obtained.
