2. Whiteboard - Wikipedia

   en.wikipedia.org/wiki/Whiteboard

   Paint varies from electron beam cured coatings to UV and other coating systems. Good commercial grade painted steel or aluminum has excellent dry erase properties and many will be able to have permanent marker cleaned from the surface. Any coated surface is susceptible to scratching. Painted steel surfaces are magnetic and allow the use of magnets.

   The paint then hardens with the magnetic field holding the particles in their magnetic pattern. Some experimentation has been done applying opposing north–south magnetic fields to opposing sides of the painted panels, causing the carbonyl iron particles to align (standing up on end so they are three-dimensionally parallel to the magnetic field).

5. Electrostatic coating - Wikipedia

   en.wikipedia.org/wiki/Electrostatic_coating

   Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. Paint, in the form of either powdered particles or atomized liquid, is initially projected towards a conductive workpiece using normal spraying methods, and is then accelerated toward the work piece by a powerful electrostatic charge.

6. Mars Black (pigment) - Wikipedia

   en.wikipedia.org/wiki/Mars_Black_(pigment)

   Mars Black is an iron oxide pigment developed in the 20th century. Also known under the names of black iron oxide, magnetic oxide, Pigment Black 11, and ferrous ferric oxide (Fe 3 O 4), [1] it has no known health hazards [2] and is considered non-toxic, with an ASTM lightfastness rating of I.

7. 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.

8. Magnetic field-assisted finishing - Wikipedia

   en.wikipedia.org/wiki/Magnetic_field-assisted...

   Magnetic field-assisted finishing, sometimes called magnetic abrasive finishing, is a surface finishing technique in which a magnetic field is used to force abrasive particles against the target surface. [1] As such, finishing of conventionally inaccessible surfaces (e.g., the inside surface of a long curved pipe) is possible.

9. Magnetorheological fluid - Wikipedia

   en.wikipedia.org/wiki/Magnetorheological_fluid

   In the absence of external pressure the maximum shear strength is about 100 kPa. If the fluid is compressed in the magnetic field direction and the compressive stress is 2 MPa, the shear strength is raised to 1100 kPa. [3] If the standard magnetic particles are replaced with elongated magnetic particles, the shear strength is also improved. [4]
