  2. Booster bag - Wikipedia

    en.wikipedia.org/wiki/Booster_bag

    A booster bag is a handmade bag used to shoplift, typically from retail stores, libraries, and any other location employing electronic security detectors to deter theft. [1] The booster bag can be an ordinary shopping bag , backpack , pocketed garment, or other inconspicuous container whose inside is lined with a special conductive material ...

  3. Faraday cage - Wikipedia

    en.wikipedia.org/wiki/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. [1]

  4. Antistatic bag - Wikipedia

    en.wikipedia.org/wiki/Antistatic_bag

    An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD). These bags are usually plastic polyethylene terephthalate (PET) and have a distinctive color (silvery for metallised film , pink or black for polyethylene ).

  5. Mechanically powered flashlight - Wikipedia

    en.wikipedia.org/wiki/Mechanically_powered...

    The linear induction, Faraday flashlight, or "shake flashlight" is another type of mechanically powered flashlight. It has been sold in the US beginning with direct marketing campaigns in 2002. This design contains a linear electrical generator which charges a supercapacitor which functions similarly to a rechargeable battery when the ...

  6. Talk:Faraday cage - Wikipedia

    en.wikipedia.org/wiki/Talk:Faraday_cage

    A shopping bag lined with aluminum foil acts as a Faraday cage. It is often used by shoplifters to steal RFID tagged items.[citation needed] In this case, the use of the bags as a Faraday cage is intentional, though paper bags lined with foil are made also for the purposes of blocking light and moisture.

  7. Optical isolator - Wikipedia

    en.wikipedia.org/wiki/Optical_isolator

    Figure 2 shows a Faraday rotator with an input polarizer, and an output analyzer. For a polarization dependent isolator, the angle between the polarizer and the analyzer, , is set to 45°. The Faraday rotator is chosen to give a 45° rotation. Polarization dependent isolators are typically used in free space optical systems.

  8. Faraday's ice pail experiment - Wikipedia

    en.wikipedia.org/wiki/Faraday's_ice_pail_experiment

    Faraday's ice pail experiment is a simple electrostatics experiment performed in 1843 by British scientist Michael Faraday [1] [2] that demonstrates the effect of electrostatic induction on a conducting container. For a container, Faraday used a metal pail made to hold ice, which gave the experiment its name. [3]

  9. Mathematical descriptions of the electromagnetic field

    en.wikipedia.org/wiki/Mathematical_descriptions...

    The most common description of the electromagnetic field uses two three-dimensional vector fields called the electric field and the magnetic field.These vector fields each have a value defined at every point of space and time and are thus often regarded as functions of the space and time coordinates.
