  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. Electromagnetic induction - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_induction

    Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field . Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction. Lenz's law describes the direction ...

  4. 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.

  5. Ultium - Wikipedia

    en.wikipedia.org/wiki/Ultium

    Ultium. Ultium architecture at Shenzhen Auto Show (June 2023), showing flat, underfloor battery module (between the wheels) and front and rear Ultium Drive units. Ultium is an electric vehicle battery and motor architecture developed by General Motors. [ 1] It is being deployed for battery electric vehicles from General Motors portfolio brands ...

  6. Eddy current - Wikipedia

    en.wikipedia.org/wiki/Eddy_current

    The Lorentz force of the magnetic field on the electrons in the metal induces a sideways current under the magnet. The magnetic field, acting on the sideways moving electrons, creates a Lorentz force opposite to the velocity of the sheet, which acts as a drag force on the sheet. The blue arrows are counter magnetic fields generated by the ...

  7. Inductive charging - Wikipedia

    en.wikipedia.org/wiki/Inductive_charging

    Inductive charging. The primary coil in the charger induces a current in the secondary coil in the device being charged. Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in ...

  8. Eddy current brake - Wikipedia

    en.wikipedia.org/wiki/Eddy_current_brake

    The brake does not work by the simple attraction of a ferromagnetic metal to the magnet. See the diagram at right. It shows a metal sheet (C) moving to the right under a magnet. The magnetic field (B, green arrows) of the magnet's north pole N passes down through the sheet. Since the metal is moving, the magnetic flux through

  9. Tesla Cybertruck - Wikipedia

    en.wikipedia.org/wiki/Tesla_Cybertruck

    The Tesla Cybertruck is a battery electric pickup truck built by Tesla, Inc. since 2023. [5] Introduced as a concept vehicle in November 2019, it has a body design reminiscent of low-polygon modelling, consisting of flat stainless steel sheet panels.
