  3. Faraday cage - Wikipedia

    en.wikipedia.org/wiki/Faraday_cage

    Animation showing how a Faraday cage (box) works. When an external electrical field (arrows) is applied, the electrons (little balls) in the metal move to the left side of the cage, giving it a negative charge, while the remaining unbalanced charge of the nuclei give the right side a positive charge. These induced charges create an opposing ...

  9. Heat shield - Wikipedia

    en.wikipedia.org/wiki/Heat_shield

    Due to the large amounts of heat given off by internal combustion engines, [4] heat shields are used on most engines to protect components and bodywork from heat damage. As well as protection, effective heat shields can give a performance benefit by reducing engine bay temperatures, therefore reducing the temperature of the air entering the engine. [5]
