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.
No, cardboard is not magnetic. Cardboard is typically made from paper fibers that do not contain magnetic properties.
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.
All planets have magnetic fields. I believe that in most cases, this magnetic field can act as a shield.
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.
Not at all well
I would suggest the use of straps
store:AC.MOORE & MICHAELSalso foil and cardboard
i need the answer too
No
