2. Magnet - Wikipedia

   en.wikipedia.org/wiki/Magnet

   A magnet's magnetic moment (also called magnetic dipole moment and usually denoted μ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, [ 15 ] and the magnitude relates to how strong and how far apart these poles ...

3. Magnetic sail - Wikipedia

   en.wikipedia.org/wiki/Magnetic_sail

   Magnetic sail animation. A magnetic sail is a proposed method of spacecraft propulsion where an onboard magnetic field source interacts with a plasma wind (e.g., the solar wind) to form an artificial magnetosphere (similar to Earth's magnetosphere) that acts as a sail, transferring force from the wind to the spacecraft requiring little to no propellant as detailed for each proposed magnetic ...

4. Artificial gravity - Wikipedia

   en.wikipedia.org/wiki/Artificial_gravity

   This form of artificial gravity is desirable because it could functionally create the illusion of a gravity field that is uniform and unidirectional throughout a spacecraft, without the need for large, spinning rings, whose fields may not be uniform, not unidirectional with respect to the spacecraft, and require constant rotation.

5. Programmable magnet - Wikipedia

   en.wikipedia.org/wiki/Programmable_magnet

   Programmed magnets can be programmed, or coded, by varying the polarity and/or field strengths of each source of the arrays of magnetic sources that make up each structure. The resulting magnetic structures can be one-dimensional, two-dimensional, three-dimensional, and even four-dimensional if produced using an electromagnetic array.

6. Magnetic levitation - Wikipedia

   en.wikipedia.org/wiki/Magnetic_levitation

   Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used. Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces. [2]

7. Superconducting magnet - Wikipedia

   en.wikipedia.org/wiki/Superconducting_magnet

   A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation.

9. Tunable metamaterial - Wikipedia

   en.wikipedia.org/wiki/Tunable_metamaterial

   A type of FSS based metamaterial has the interchangeable nomenclature Artificial Magnetic Conductor (AMC) or High Impedance Surface (HIS). The HIS, or AMC, is an artificial, metallic, electromagnetic structure. The structure is designed to be selective in supporting surface wave currents, different from conventional metallic conductors.
