Faraday cage magnetic fields

  1. Sep 8, 2015 #1
    Can a cylinder with 1 side open act as a faredey cage (which do not allow passage of magnetic field) when magnetic field are only coming parallel to the curved part

    A Faraday cage is used for shielding electric fields, not magnetic fields. You would use ferrous metal and/or mu-metal for shielding against B-fields.

    And if your shield shown in the upside-down picture were made of ferrous metal, it would be able to shield some of the external B-field. You will still get some field curving in and out of the open end, however.
