2. Staple (fastener) - Wikipedia

   en.wikipedia.org/wiki/Staple_(fastener)

   A staple (from which the paper fastener was developed) A staple is a type of two-pronged fastener, usually metal, used for joining, gathering, or binding materials together. Large staples might be used with a hammer or staple gun for masonry, roofing, corrugated boxes and other heavy-duty uses. Smaller staples are used with a stapler to attach ...

3. Ferrite (magnet) - Wikipedia

   en.wikipedia.org/wiki/Ferrite_(magnet)

   Ferrite (magnet) A stack of ferrite magnets, with magnetic household items stuck to it. A ferrite is one of a family of iron oxide -containing magnetic ceramic materials. They are ferrimagnetic, meaning they are attracted by magnetic fields and can be magnetized to become permanent magnets. Unlike many ferromagnetic materials, most ferrites are ...

4. Stapler - Wikipedia

   en.wikipedia.org/wiki/Stapler

   A spring-loaded stapler. A stapler is a mechanical device that joins pages of paper or similar material by driving a thin metal staple through the sheets and folding the ends. Staplers are widely used in government, business, offices, workplaces, homes, and schools. [1]

5. Fastener - Wikipedia

   en.wikipedia.org/wiki/Fastener

   Fastener. A fastener (US English) or fastening (UK English) [1] is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. [2] Steel fasteners are usually made of ...

6. Electromagnetic shielding - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_shielding

   For static or slowly varying magnetic fields (below about 100 kHz) the Faraday shielding described above is ineffective. In these cases shields made of high magnetic permeability metal alloys can be used, such as sheets of permalloy and mu-metal [9] [10] or with nanocrystalline grain structure ferromagnetic metal coatings. [11]

7. Halbach array - Wikipedia

   en.wikipedia.org/wiki/Halbach_array

   A Halbach array (German: [ˈhalbax]) is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. [ 1 ][ 2 ] This is achieved by having a spatially rotating pattern of magnetisation. The rotating pattern of permanent magnets (on the front face ...

8. Brass fastener - Wikipedia

   en.wikipedia.org/wiki/Brass_fastener

   A brass fastener, butterfly clips, brad, paper fastener or split pin is a stationery item used for securing multiple sheets of paper together. A patent of the fastener was issued in 1866 to George W McGill. [1] The fastener is inserted into punched holes in the stack of paper, and the leaves, or tines, of the legs are separated and bent over to ...

9. Magnetic levitation - Wikipedia

   en.wikipedia.org/wiki/Magnetic_levitation

   Maglev, or magnetic levitation, is a system of transportation that suspends, guides and propels vehicles, predominantly trains, using magnetic levitation from a very large number of magnets for lift and propulsion. This method has the potential to be faster, quieter and smoother than wheeled mass transit systems.
