2. Domain wall (magnetism) - Wikipedia

   en.wikipedia.org/wiki/Domain_wall_(magnetism)

   In magnetism, a domain wall is an interface separating magnetic domains. It is a transition between different magnetic moments and usually undergoes an angular displacement of 90° or 180°. A domain wall is a gradual reorientation of individual moments across a finite distance. The domain wall thickness depends on the anisotropy of the ...

3. Via fence - Wikipedia

   en.wikipedia.org/wiki/Via_fence

   Via fences are used to shield microstrip and stripline transmission lines, guard edges of printed circuit boards, shield functional circuit units from each other, and to form the walls of waveguides integrated into a planar format. Via fences are cheap and easy to implement, but use up board space and are not as effective as solid metal walls.

4. Electromagnetic suspension - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_suspension

   Floating globe. Magnetic levitation with a feedback loop. Electromagnetic suspension (EMS) is the magnetic levitation of an object achieved by constantly altering the strength of a magnetic field produced by electromagnets using a feedback loop. In most cases the levitation effect is mostly due to permanent magnets as they have no power ...

5. 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]

6. Domain wall - Wikipedia

   en.wikipedia.org/wiki/Domain_wall

   A domain wall is the boundary between two neighboring domains. Thus a domain wall is extended in two spatial dimensions and one time dimension. Important examples are: Domain wall (magnetism), an interface separating magnetic domains; Domain wall (optics), for domain walls in optics; Domain wall (string theory), a theoretical 2-dimensional ...

7. Magnetic anisotropy - Wikipedia

   en.wikipedia.org/wiki/Magnetic_anisotropy

   A magnetic particle with triaxial anisotropy still has a single easy axis, but it also has a hard axis (direction of maximum energy) and an intermediate axis (direction associated with a saddle point in the energy). The coordinates can be chosen so the energy has the form
