  2. Electromagnetic shielding - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_shielding

    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 electrical devices from their surroundings, and to cables to isolate wires from the environment ...

  3. Electromagnetic interference - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_interference

    Electrical ignition systems, such as in gasoline engines. Continual switching actions of digital electronic circuitry. Conducted electromagnetic interference is caused by the physical contact of the conductors as opposed to radiated EMI, which is caused by induction (without physical contact of the conductors).

  4. Shielded cable - Wikipedia

    en.wikipedia.org/wiki/Shielded_cable

    Four-conductor shielded cable with metal foil shield and drain wire. Coaxial cable. Electronic symbol for a shielded wire. A shielded cable or screened cable is an electrical cable that has a common conductive layer around its conductors for electromagnetic shielding. [1] This shield is usually covered by an outermost layer of the cable.

  5. Electric-field screening - Wikipedia

    en.wikipedia.org/wiki/Electric-field_screening

    In atomic physics, a germane effect exists for atoms with more than one electron shell: the shielding effect. In plasma physics, electric-field screening is also called Debye screening or shielding. It manifests itself on macroscopic scales by a sheath (Debye sheath) next to a material with which the plasma is in contact.

  6. Cathodic protection - Wikipedia

    en.wikipedia.org/wiki/Cathodic_protection

    Also, the NACE SP0169:2007 standard defines shielding in section 2, cautions against the use of materials that create electrical shielding in section 4.2.3, cautions against use of external coatings that create electrical shielding in section 5.1.2.3, and instructs readers to take 'appropriate action' when the effects of electrical shielding of ...
