What else can I help you with?
If you are given some iron fillings and a magnet describe how you would find the poles of the magnet?
If possible cover the magnet with a sheet of paper and gently sprinkle the iron filings over the sheet ot paper, they will stick in a pattern following the magnetic "lines of flux" which will get closer and closer near the poles of the magnet. Afterwards you can cleanup by lifting the sheet of paper off of the magnet and the filings will fall away. Without the paper the filings will usually become tightly stuck to the magnet, making it hard to clean.
Does the amount of iron filings in water effect waves when a magnet passes over?
No, the amount of iron filings in water does not affect waves when a magnet passes over. The iron filings would be attracted to the magnet, creating a visual effect, but they do not disrupt the propagation of waves in the water.
How do you separate iron filings from lead filings?
Iron is a ferrous material, and aluminum is non-ferrous. A magnet would separate the two materials as the iron would be attracted to the magnet while the aluminum filings would not. The term ferrous basically refers to any material which contains iron.
Describe two ways that you can separate iron filings that are accidentally dropped into a mixture of salt crystals and water?
One way to separate iron filings from a mixture of salt crystals and water is to use a magnet. The iron filings will be attracted to the magnet, allowing for easy separation. Another method is to use filtration. By pouring the mixture through a filter paper, the iron filings will be retained on the filter paper while the salt crystals and water pass through.
Which method is appropriate for separating a mixture of iron and aluminum?
You could do this using a magnet, Iron filings are attracted to a magnet, aluminium filings are not.Hint: magnetism, investigate the relative magnetic properties of the metals.Iron is a ferrous material, and aluminum is non-ferrous. A magnet would separate the two materials as the iron would be attracted to the magnet while the aluminum filings would not. The term ferrous basically refers to any material which contains iron.

How would you use the method of iron filings to determine whether lines of force pass through such materials as glass wood and copper?
Hold the magnet under a flat piece of glass. Sprinkle on some filings. Move the magnet. If the lines of force penetrate the glass, the filings will move. If they don't, the filings won't move. Repeat with each material being investigated and record the results. When finished, summarize observations.
What materials are use to 'see' the field lines around a magnet?
First sprinkle iron filings on a glass plate well scattered. Now place a bar magnet under the surface of the glass plate and give light jerks continuously to the plate. Gradually the iron filings would be arranged in curved lines. More filings are found concentrated near by the poles. These curved strutures stand for the magnetic lines in the vicinity of the magnet. Actually magnetic lines of force are only imaginary lines.
How would you separate iron filings and aluminum filing?
One way to separate iron filings and aluminum filings is by using a magnet. Since iron is magnetic but aluminum is not, you can use a magnet to attract the iron filings and separate them from the aluminum filings easily. Simply pass the magnet over the mixture, and the iron filings will be attracted to the magnet, allowing you to separate them from the aluminum filings effectively.
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.
Does the amount of iron filings in water effect waves when a magnet passes over?
No, the amount of iron filings in water does not affect waves when a magnet passes over. The iron filings would be attracted to the magnet, creating a visual effect, but they do not disrupt the propagation of waves in the water.
How do you separate iron filings from lead filings?
Iron is a ferrous material, and aluminum is non-ferrous. A magnet would separate the two materials as the iron would be attracted to the magnet while the aluminum filings would not. The term ferrous basically refers to any material which contains iron.
Could separate iron filings from copper sulphate and copper oxide with a magnet?
Yes, a magnet would remove the iron filings without attracting the copper salts, copper salts are not magnetic.
What physical properties would you use to separate a mixture of soil and iron filings?
A magnet can be used to separate iron filings from soil due to the magnetic properties of iron. Simply pass the magnet over the mixture to attract and separate the iron filings from the soil.
What physical property would allow you to seprate a mixture of iron filings and soil?
Magnet
How do you separate a mixture of sand and iron filings?
By using a magnet to separate the iron filings, you'd be left with the sulfur and sand mix. Selecting a solvent for the sulfur will allow you to dissolve the sulfur, and then all you have to do is put the sand in a filter and wash the sulfur through with the solvent.
How would you separate copper strands and iron filings?
One way to separate copper strands and iron filings is by using a magnet. Copper is not magnetic but iron is, so you can use the magnet to attract and separate the iron filings from the copper strands. Alternatively, you could also use the difference in density between copper and iron to physically separate them using techniques like flotation or panning.
