Why sprinkling iron filings in magnetic field on the cardboard around the wire they will align themselves in concentric circle?
When iron filings are sprinkled around a wire carrying an electric current, they align themselves along the magnetic field lines created by the current. The magnetic field generated by the current follows a circular pattern around the wire, and the magnetic properties of the iron filings cause them to respond to this field. As a result, the filings arrange themselves in concentric circles, visually demonstrating the shape and direction of the magnetic field around the wire. This phenomenon illustrates the relationship between electricity and magnetism, as described by Ampère's law.

Can magnetic force pass through cardboard ramp?
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.
Although copper and aluminum are not magnetic why is a sheet of either metal more difficult to pass between the pole pieces of a magnet than a sheet of cardboard?
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.
How is strength of a magnet affected by cardboard?
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.
What is the list for the characteristics of a magnetic field produced by a current?
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.
Can magnetic force pass through cardboard?
Depending on the size of the magnets, yes, it's possible.
How can you detect a magnet?
With a magnet or by sprinkling iron fillings an cardboard if you use it to see the pattern of magnetic field.
Is cardboard magnetic?
No, cardboard is not magnetic. Cardboard is typically made from paper fibers that do not contain magnetic properties.
Why do Concentric circles arrange around a current carrying conductor only if the cardbord is tapped gently?
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.

Does cardboard act as a magnetic shield?
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.
How do magnets work threw cardbord?
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.
What happens when you place a sheet of cardboard with iron filings perpendicular to a current carrying wire?
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.
What you can make visible by sprinkling iron fillings around a magnet?
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.
Can magnets pass through cardboard?
Provided the cardboard is not too thick, a magnet on each side will attract each other.

How can iron filings be used to demonstrate magnetic field lines?
Iron filings can be used to demonstrate magnetic field lines by sprinkling them around a magnet. The filings align along the magnetic field lines, making the invisible magnetic field visible.
