Yes, I agree with you (y33t), but how is it in situation: We have for example positive charged sphere with cavity made of isulation material. Is there electric field in the cavity?

Hi, Forget the faraday cage. The basic question is: The blown sphere from dielectric (isolant) material is in electrostatic field (no electromagnetic waves).Is there inside the sphere electrostatic field or not?

Hello, This is simple question, but I didnt find the clear answer e.g. on the web pages: How Faraday cage works in electric field is clear. 1. The metal blown sphere = faraday cage in electric field - inside the sphere is not electric field. 2. But how is it when the blown sphere is...
