HI
Assume we have a point charge in the center of a shell, now the inside inner wall will get an opposite charge and the outer side of the shell will have the same charge as the point charge. Since we have a charge on the out side, how isn't there any fields outside ?? how are we protected from micro oven for example ? I don't get it no matter how much I read.
Im sorry but I am very confused, I understand how faraday cages protect against external e fields. But, How come e-fields don't escape a faraday cage when the outer shell charge exist and is directly related to the inner point charge??
thanks
