    Faraday cages cannot block stable or slowly varying magnetic fields, such as the Earth’s magnetic field (a compass will still work inside one). To a large degree, however, they shield the interior from external electromagnetic radiation if the conductor is thick enough and any holes are significantly smaller than the wavelength of the radiation

    I’m certainly no expert, but something tells me the cage in OP’s pic doesn’t fit the criteria to act as a faraday cage.

    E: Nope, I’m wrong. u/deegeese has informed me on how big the wavelength is.
