No its not
I believe cardboard is a conductor, and cardboard is not that thick to block the magnetic energy.
Place a cardboard along the cross-section of wire and hold the cardboard horizontally and put iron powder on it and pass current through the wire...the powder will align itself in shape of magnetic field. Another method you can try is on cardboard place a magnetic compass and the needle will align itself in the path of magnetic field and keep marking the position of needle.
Because of the magnetic force
The electric force
All planets have magnetic fields. I believe that in most cases, this magnetic field can act as a shield.
No its not
does magnetic forces pass through cardboard? <><><><> Very easily. Lay a paperclip on a sheet of cardboard. Place a magnet beneath the cardboard. When you move the magnet, the paperclip will also move.

No, a magnet will not be able to attract a paper clip that has a cardboard between them. The cardboard will act as a barrier, preventing the magnetic force from reaching the paper clip.
