2. Electromagnetic shielding - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_shielding

   Electromagnetic shielding. Electromagnetic shielding cages inside a disassembled mobile phone. In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials. It is typically applied to enclosures, for isolating ...

3. Faraday cage - Wikipedia

   en.wikipedia.org/wiki/Faraday_cage

   Faraday cage. A Faraday cage or Faraday shield is an enclosure used to block some electromagnetic fields. A Faraday shield may be formed by a continuous covering of conductive material, or in the case of a Faraday cage, by a mesh of such materials. Faraday cages are named after scientist Michael Faraday, who first constructed one in 1836.

4. E-M-F Company - Wikipedia

   en.wikipedia.org/wiki/E-M-F_Company

   E-M-F Company. The E-M-F Company was an early American automobile manufacturer that produced automobiles from 1909 to 1912. The name E-M-F was gleaned from the initials of the three company founders: Barney Everitt (a custom auto-body builder from Detroit ), William Metzger (formerly of Cadillac ), and Walter Flanders (who had served as Henry ...

5. Electromagnetic radiation and health - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_radiation...

   The field strength of electromagnetic radiation is measured in volts per meter (V/m). [2] : 139. The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States. [3] [4]

6. Counter-electromotive force - Wikipedia

   en.wikipedia.org/wiki/Counter-electromotive_force

   That is, the back-EMF is also due to inductance and Faraday's law, but occurs even when the motor current is not changing, and arises from the geometric considerations of an armature spinning in a magnetic field. This voltage is in series with and opposes the original applied voltage and is called "back-electromotive force" (by Lenz's law).

7. Electromagnetic compatibility - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_compatibility

   Electromagnetic compatibility. Anechoic RF chamber used for EMC testing (radiated emissions and immunity). The furniture has to be made of wood or plastic, not metal. Electromagnetic compatibility ( EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional ...
