Want this question answered?
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.
A magnetic field is a change in energy within a volume of space. A magnetograph can be created by placing a piece of paper over a magnet and sprinkling the paper with iron filings. The particles align themselves with the lines of magnetic force produced by the magnet. The magnetic lines of force show where the magnetic field exits the material at one pole and reenters the material at another pole along the length of the magnet. It should be noted that the magnetic lines of force exist in three dimensions but are only seen in two dimensions in the image.
Depending on the size of the magnets, yes, it's possible.
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.
With a magnet or by sprinkling iron fillings an cardboard if you use it to see the pattern of magnetic field.
No its not

The magnetic forces that cause the iron filings to align to the magnetic field are very weak and have trouble overcoming the forces of friction. When you tap the cardboard the filing jump up a bit and while they are in the air they are able to then rotate.
By sprinkling iron fillings around a magnet the magnetic field can be shown. If the magnet is the opposite charge then the iron they will be repelled by the magnet showing how far the magnetic field reaches.
I believe cardboard is a conductor, and cardboard is not that thick to block the magnetic energy.
concentric circles around the wire
store:AC.MOORE & MICHAELSalso foil and cardboard
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.
when ever a current pass trough a conductor a magnetic field will be produced around that conductor in the for of concentric circles.

When Earth's magnetic poles have reversed themselves.
