A faraday cage is an important tool for some scientists at the MagLab. But they don’t work with it — they work inside it.

excellent explainer on how a Faraday cage works. And even the fact that electro-magnetic waves are a combo of electric field wave and a magnetic field wave, 90 degrees or orthogonal to each other, and one feeds the other (as the magnetic field is collapsing it generates the electrical field wave & vice-versa?? but where are the losses? my guess is these are waves in fields, and as such don’t have any resistance to change, so no losses generated (in the electrical, a current needs a resistance to make heat via I^2R, perhaps something called reluctance in the magnetic domain? ) and there are no losses?
