A Faraday cage is a passive thing, it does not generate a field, it converts
the EM-radiation into an electrical current.
It is not a complicated thing, it is merely a wiremesh in the form of a cage
(round, square) it's shape does not matter much, as long as it is closed.
The general theory is that as soon as a difference in fieldstrength is
present between two points of the cage, the electric current will resolve that.
The size of the mesh is important, the smaller the mesh size, the better it
protects against high frequencies.
By the way, why do we need alternating magnetic fields, or are constant
magnetic fields possible too?
