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.

As with other building materials, knowledge of the history of the construction can help you eliminate some materials that are too new to contain asbestos. For the rest, the only way to determine with certainty if asbestos is present is to have a sample sent to a lab and examined microscopically. Many materials can be examined in a polarized light microscope to determine whether and how much asbestos is present. However, because of the way flooring materials are made, it is usually necessary to examine the same with an electron microscopy to be certain that asbestos is not present.
