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.
Not at all, apart from their ability to maintain a distance between the magnet and anything magnetic.
glass it will have less magnatisim plastic is next then cardboard
Maybe?It only matters what kind of cardboard it is!
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.
They are bar magnet ,horse shoe magnet ,lime stone magnet.
Gf
I had a stroke and it apparently affected my tastebuds so everything tasted like cardboard.
NO!!! the strength of magnet is not affected by temperature
NO!!
Of course that has a great effect since as the magnet strength increase the number of magnetic flux lines increase increasing the induced electromotive force but motion of magnet is needed.

Not really the saltwater does not change give any affect the strength of a magnet reason water is totally non magnetic but when we have added some salt into it.The salty water solution has ions now it could be very good conducter if we place electricity in it.Then it could be possible the strength of a natural magnet can be affected a bit.........But i dont think normal salt water could give affect the strength of a magnet
Yes it does!
With a magnet or by sprinkling iron fillings an cardboard if you use it to see the pattern of magnetic field.

A. A magnet has a Curie Point, a temperature beyond which it is no longer a magnet. Identified by Marie Curie. This property is used in items such as toaster timers. As far as I know there is no low temperature limit.
Provided the cardboard is not too thick, a magnet on each side will attract each other.
The strength of a scrap heap magnet vary depending on the strength of the current or number of "turns" in its primary coil. Increasing either or both of these makes the magnet stronger.
To increase the strength of a magnet you need to stack it between two stronger magnets or electromagnets. To weaken it, you'd have to heat it up, or use the same method as when strengthening, only this time you should flip the magnet so it would repel the stronger (electro)magnets.
