Based on the answers from my other post², I think a faraday cage does only affect/shield from outside to inside, not from inside to outside. Am I rong ?

Magnetic shielding made with high-permeability alloys like mu-metal works not by blocking magnetic fields but by providing a path for the magnetic field lines around the shielded area. (this would explain why you can´t see then the area, the area is still there in the astral) Thus, the best shape for shields is a closed container surrounding the shielded space. The effectiveness of mu-metal shielding decreases with the alloy's permeability, which drops off at both low field strengths and, due to saturation, at high field strengths. Thus, mu-metal shields are often made of several enclosures one inside the other, each of which successively reduces the field inside it. Because mu-metal saturates at such low fields, sometimes the outer layer in such multilayer shields is made of ordinary steel. Its higher saturation value allows it to handle stronger magnetic fields, reducing them to a lower level that can be shielded effectively by the inner mu-metal layers. (If I understand right this could mean only electromagnetic forces from outside, get shielded from the inside to the outside could be non effected/or atleast way less)
