No its not
No, cardboard does not act as a magnetic shield. Magnetic shields are typically made of materials with high magnetic permeability, such as mu-metal or ferrite. Cardboard does not have the properties necessary to shield against magnetic fields.
Magnets can attract objects through cardboard because cardboard is not a material that blocks the magnetic field. The magnetic field generated by the magnet can easily pass through the cardboard and interact with other magnetic objects on the opposite side.
Provided the cardboard is not too thick, a magnet on each side will attract each other.
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.
The iron filings will align themselves along the magnetic field lines produced by the current, forming a visible pattern on the cardboard. This demonstrates the presence of a magnetic field around the current-carrying wire.
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.

Magnetic field are unaffected by those materials. Magnets and electrical fields in general are only effected by other magnetic fields. Think of a compass that is brought near another magnet. Magnetic fields are exponential in strength meaning that they are most strong at the surface and quickly fade with distance. Dont have the equation but its simple and straight forward. So if you want a magnetic field to extend through a thick (5mmm) cardboard or plastic you will need larger more powerful magnets such as rare earth or neodymium magnets. Its really about the strength of the magnet and the distance of the magnetic field. Hope that helps.
With a magnet or by sprinkling iron fillings an cardboard if you use it to see the pattern of magnetic field.

Depending on the size of the magnets, yes, it's possible.
Even though copper and aluminum are not magnetic themselves, they can interact with magnetic fields. In the case of a magnet, the changing magnetic field induces eddy currents in the metal sheet, creating a magnetic field of its own that opposes the magnet’s field. This dynamic interaction results in the resistance you feel when trying to pass a metal sheet between the pole pieces of a magnet, unlike with a non-magnetic material like cardboard.
The reason is because of the magnetic fields of the north and south poles
