Faraday guides

Pillar explainers for the Faraday category. Each guide links to products, brands, and the lab method. We do not invent attenuation numbers here.

• How Faraday cages work

  A Faraday cage is a conductive enclosure that is closed. Bags, pouches, tents, and rooms are all cages if the material and the seams complete the circuit. An open zipper is not a cage.

• How to test a Faraday bag

  A phone that loses signal in a bag is a useful smoke test. It is not a shielding-effectiveness score. Faraday Zone will publish both: a field check anyone can repeat, and a dated lab method for scores.

• EMP Faraday bags vs privacy Faraday bags

  People search “Faraday bag” for two jobs that should not share one product page: keep a phone off the network today, or store electronics against a high-altitude EMP. Faraday Zone splits them.
