Question

Does anyone have the description of iron fillings... 10 points if you do?

Answer 1

Iron filings are black and vary greatly in size and shape, though they are rarely more than 6 mm long, and will average 1-2 mm wide by 1 mm thick.

They are made by using a file on iron, hence the name filings.

Answer 2

Iron fillings are a black metalic powder-like substance created when iron metal is ground down by a metal file or similar cutting tool.  

Iron fillings are often used to observe the lines of a magnetic field.

Answer 3

It is grey and you fill it in a decay in your tooth.

Answer 4

They don't use iron fillings for teeth any more. Too much corrosion. It's usually gold or silver.

Iron filings, however, are small chips of metal. Can be used for all sorts of stuff, from iron supplements in your yard, to putting on the floor of your sister's bathroom at night so it hurts the bare feet in the morning.
