    And just to compound your embarrasment, a Faraday cage
    is for electric fields.

    Above can lead to misunderstanding.
    Faraday Cage is used to shield electro-magnetic-waves, like radio waves.

    The pulsating magnetic waves generate electicity in metals like wires and circuit boards.
    Higher the frequency to be shielded, the smaller the cage-holes. Hi freq have short wave lengths.

    Sun spots produce magnetic waves, sometimes poweful enough to overload powerlines with electricity, which trips circuit breakers.

    Pulsating magnetic lines is how municiple electricity is generated. Wires are spun in a magnetic field to generate electricty in the spinning wires (alternator) .

    Conversly, movement is generated by electrified wires in a magnetic field (motors).

    Magnetic Shields are usually a capped cylinder made of iron alloy.
    Magnetic fields take the path of least resistance thus, they flow in the iron and not in the air inside the capped cylinder.
