Copper filings are not attracted to a magnet, as iron filings are.

How do you extract copper from copper II oxide?
this is the best way for making copper oxide Get some copper and grind it up as small as possible. Once the filings are small enough, place them on a flat backing tray type thing (I found something which is use for cakes, it only needs to be flat and the size of a frying pan) Then go to the kitchen and find the biggest element on the stove, turn it up to full and place you pan thingy with the filings on it. After a few minutes you will start to see the filings change color, every now and then you will want to give the filings a toss and shake. You will want to keep the filings on the heat until they stop changing color. I did this with copper filings (the copper filings were half oxidized in the oven, which took hours. When I put them on the element it was done in about 10minutes! It may take a bit longer as my filings were half oxidized, but they were larger filings so this could take about the same time)
If a stationary electron sat inside a stationary magnetic field would the magnetic field cause the electron to move?
Stationary charge don't produce a magnetic field. because it has no velocity in it, without flow of electron we can't find electricity and for that we have no magnetic field for a stationary charge. It produce only electric field.
How can you see magnetic lines?
The magnetic lines of force are invisible, you can not see them; but you can do the following experiment that will show you the effect that the magnetic lines of force have on iron filings.Here is a simple experiment to observe magnetic lines of force from a magnet.Take a piece of cardboard and tape a bar magnet on one side.Now flip over the board and keep it horizontal such that the magnet is on the lower side.Place some white paper on top of the board and use clips, staples, tape or glue to keep it in place.Now lightly sprinkle some iron filings on the paper. They would arrange themselves randomly at first.Now, keep tapping the edge of the board very lightly, just enough to make the iron filings move a little.After a while, you will see the iron filings arrange themselves in a pattern. The pattern will be made up of somewhat elliptical (or circular) lines from one pole of the magnet to the other.These lines are where the invisible magnetic lines of force are located.They never intersect each other because the magnetic field of the magnet acts to repel each other.
What is fossil magnetism?
In hot Iron bearing rocks or magmas the iron minerals they contain align themselves parallel to the Earth's magnetic field. When they cool below about 500 degrees Celsius the the iron minerals 'freeze' in this magnetic orientation and are no longer able to adapt to any changes in the Earth's field (which occasionally reverses polarity and wanders). This frozen magnetic alignment is a fossil of the ancient magnetic field and can be 'read' to find out what the Earth's magnetic field has been doing in the past.
Can astronomers learn the magnetic field of a star?
Light that comes from the sun is polarized by these magnetic fields. A meter can determine the different directions of the light and detect interference. This interference is known as a magnetic field.
How do you find the shape of a magnetic field using a compass?
Yes. I can be done using iron filings and a clear piece of plastic. Pour on the iron filings, put on the plastic, and then the magnet. The iron filings should form the shape of the magnetic field around it. If that does not work, here is a link to a picture... http://www.fi.edu/htlc/teachers/lettieri/magneticfields.jpg Hope that helps.

How do you find magnetic field in Pokemon diamond?
if its a magnetic field for evolving nosepass and magneton then just level it up in mt coronet
How yo find the magnetic field of earth at a particular place?
Using a compass is the easiest way. The needle is going to point to the Magnetic North Pole. That means that the compass needle is ALIGNED with the Magnetic Field Lines of the Earth's magnetic field at your current position.
How a compass works and why it is useful?
A compass has a magnet that points north, according to the Earth's magnetic field. It is useful, precisely, to find out where north is.A compass has a magnet that points north, according to the Earth's magnetic field.

If a stationary electron sat inside a stationary magnetic field would the magnetic field cause the electron to move?
Stationary charge don't produce a magnetic field. because it has no velocity in it, without flow of electron we can't find electricity and for that we have no magnetic field for a stationary charge. It produce only electric field.
How do you find magnetic field?
One of the easiest ways to detect a magnetic field is with a length of conductive material attached to a voltage meter. The presence of a magnetic field causes an electrical current to flow through the conductor, thus causing a spike on the meter.
Are quarters magnetic?
U.S. quarters are made of copper and nickel so they're not magnetic. But you did try to use a magnet on one to find out, of course.... Canadian quarters are made of nickel or steel depending on their age, so they are magnetic.
What to do if you spill iron filings in your house?
So, I recently bought an hourglass that had magnetic sand/iron filings but the glass broke. I cleaned up most of it and put it in few plastic bags and cleaned up as much as I could with a magnet and vacuumed as well. Is there a way for me to find out if I got it all or any other suggestion?

A sphere of linear magnetic material is placed in an otherwise uniform magnetic field Bo find the new field inside the sphere?
This is a homework assignment not a proper question. WikkiAnswers answers questions, it will not do your homework assignments for you.
