What else can I help you with?
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.
How can you see the magentic field formed around wires containig electricity?
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.
How can it be shown that a magnetic field exists around a wire through which a direct current is passing?
Take 1/4 in bolt that is 2 to 4 inches long and wrap it with 20 to 50 windings of small guage insulated wire, hook up each end to the terminals on a small 9 volt transister battery. Hold or move the bolt under a piece of paper that has a sprinkling of iron filings on it. The filings will align to the magnet lines of flux.
Are iron filings magnetic?
Yes, iron filings are magnetic.
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.

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
Are iron filings magnetic?
Yes, iron filings are magnetic.
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.
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.
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.
Is unheated sulfur and iron filings is substance or mixture?
Sulfur and iron filings together are a mixture.
