  2. 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]

  3. Everhart–Thornley detector - Wikipedia

    en.wikipedia.org/wiki/Everhart–Thornley_detector

    The E-T secondary electron detector can be used in the SEM's back-scattered electron mode by either turning off the Faraday cage or by applying a negative voltage to the Faraday cage. However, better back-scattered electron images come from dedicated BSE detectors rather than from using the E–T detector as a BSE detector.

  4. Electromagnetic shielding - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_shielding

    The door of a microwave oven has a screen built into the window. From the perspective of microwaves (with wavelengths of 12 cm) this screen finishes a Faraday cage formed by the oven's metal housing. Visible light, with wavelengths ranging between 400 nm and 700 nm, passes easily through the screen holes.

  5. Homopolar generator - Wikipedia

    en.wikipedia.org/wiki/Homopolar_generator

    Faraday disc. The first homopolar generator was developed by Michael Faraday during his experiments in 1831. It is frequently called the Faraday disc or Faraday wheel in his honor. It was the beginning of modern dynamos — that is, electrical generators which operate using a magnetic field.

  6. Pure homopolar generator - Wikipedia

    en.wikipedia.org/wiki/Pure_homopolar_generator

    A pure homopolar generator (PHG) [1] [2] [3] is an electric generator not requiring brushes or electronics or semiconductor parts to convert torque into direct current.In other words, this homopolar generator only requires theoretical homogeneous or actual (constantly or cyclically) homogenized magnetic field to be able to produce direct current.

  9. Faraday's ice pail experiment - Wikipedia

    en.wikipedia.org/wiki/Faraday's_ice_pail_experiment

    The inner cylinder is the Faraday pail container itself, separated from the outer cylinder with insulating supports. The outer cylindrical metal screen surrounds the inner, and acts as a ground to shield it from stray charges. This design largely eliminates the stray charge problem, as well as allowing the experimenter to see inside the container.
