Why do Concentric circles arrange around a current carrying conductor only if the cardbord is tapped gently?
When a cardboard is tapped gently, it produces a small current in the wire which creates a magnetic field around the conductor. This magnetic field induces circular electric currents in the cardboard, resulting in the formation of concentric circles around the current-carrying conductor. The tapping action is essential to generate the initial current flow and establish the magnetic field.
How can it be shown that a magnetic field exists around a wire through which a direct current is passing?
A magnetic field around a wire carrying a direct current can be demonstrated using a compass needle. When the compass is placed near the wire, its needle will deflect perpendicular to the wire's direction, indicating the presence of a magnetic field. Alternatively, iron filings sprinkled around the wire will align in patterns that indicate the field's shape.
How can you see the magentic field formed around wires containig electricity?
You can visualize the magnetic field around wires containing electricity by using iron filings. Sprinkle iron filings around the wire, and they will align with the magnetic field lines, showing the pattern of the magnetic field. Another way is to use a magnetic field viewing film, which changes color based on the strength of the magnetic field.
Do the dry and wet iron filings show the same physical properties?
Dry iron filings and wet iron filings have different physical properties. Dry iron filings are free-flowing and easily spread out, while wet iron filings clump together due to the presence of water. Additionally, wet iron filings may rust more easily due to the moisture content.
Is the mixture of iron filings homogeneous or heterogeneous?
A mixture of iron filings is homogeneous, meaning it has a uniform composition throughout. This is because iron filings are small particles that mix evenly with each other, leading to a consistent appearance and properties in the mixture.

How do you separate sand grains and iron filings using a magnet?
Well it's fairly easy. First, get a piece of cardboard and a small box that you can later throw away. Gather together the sand grains and iron filings into one spot, then, with a piece of cardboard spread the mix into a thin layer. (Use cardboard to avoid cutting your hands on the metal filings.) Hold the magnet just above the layer, sweeping it across the layer in a straight line. As the filings attach to the magnet, use cardboard edge to wipe them off the magnet into the cardboard box. Repeat with magnet over the layer, and again wipe the filings into the box. Repeat until the sand is fairly clean. Use a dustpan to clean up the sand.

Why are iron filings used to find the magnetic field when copper filings are not?
Copper filings are not attracted to a magnet, as iron filings are.
What is the difference between cross filings and draw filings?
cross filings remove materials and draw filings smooths it down that's what i read anyway
What is the density of aluminum filings?
The density of pure aluminum is 2.7.Filings have a packing ratio of roughly 0.6 so the density of the filings is about 1.6. this of course depends greatly on the size and shape of the filings.
How are business filings usually organized?
Business filings are usually organized into three separate sections. The sections would be action, reference, and archive. Action would be the current files. Reference would be those one would find on occasion. Archive would be for retention.
Separate iron filings and aluminum filings?
Aluminum and iron can be differentiated because iron is magnetic and aluminum is not. To separate them, expose the filings to a magnetic source and the iron will separate.
How do you separate iron and copper filings?
One way to separate iron and copper filings is by using a magnet. Since iron is magnetic, you can use a magnet to attract and separate the iron filings from the copper filings, which are not magnetic. Alternatively, you can dissolve the mixture in a solvent, filter out the copper filings, and then evaporate the solvent to retrieve the iron filings.
What is the separation method for iron filings and sulphur to obtain iron filings?
One method to separate iron filings and sulfur is to use a magnet. The iron filings are attracted to the magnet and can be easily separated from the sulfur. This method takes advantage of the magnetic properties of iron filings.
