2. Magna-Tiles - Wikipedia

   en.wikipedia.org/wiki/Magna-Tiles

   Magna-Tiles are a construction toy system. The pieces are plastic tiles of varying shapes that snap together magnetically , allowing users to build various geometric structures. Magna-Tiles were originally developed in Japan , where they were sold under the name Pythagoras .

3. Plasma-facing material - Wikipedia

   en.wikipedia.org/wiki/Plasma-facing_material

   In nuclear fusion power research, the plasma-facing material (or materials) (PFM) is any material used to construct the plasma-facing components (PFC), those components exposed to the plasma within which nuclear fusion occurs, and particularly the material used for the lining the first wall or divertor region of the reactor vessel.

4. Wendelstein 7-X - Wikipedia

   en.wikipedia.org/wiki/Wendelstein_7-X

   The 50 non-planar coils are used for adjusting the magnetic field. It aims for a plasma density of 3 × 10 20 particles per cubic metre, and a plasma temperature of 60–130 megakelvins (MK). [1] The W7-X is optimised along the quasi-isodynamic principle. [10] The main components are the magnetic coils, cryostat, plasma vessel, divertor and ...

5. Radiation-absorbent material - Wikipedia

   For low frequency damping, this distance is often 60 cm (24 in), while high-frequency panels are as short as 7.5 to 10 cm (3 to 4 in). Panels of RAM are typically installed on the walls of an EMC test chamber with the tips pointing inward to the chamber. Pyramidal RAM attenuates signal by two effects: scattering and absorption.

7. 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 ...
