Question:

What could I measure with my magnetic money experiment?

Okay, well I‘m doing this science experiment. My variables are the two types of magnets. One is just a regular magnet and the other is a neodymium magnet. So I lay down the dollar bill and first see if the regular magnet works (it won‘t). Then I take the neodymium magnet and see if it attracts the dollar (it will). But I have no idea what I could measure on this experiment. Maybe how far the dollar bill lifts off the table? But I really probably need something else. Any help, please?

Answer:

Paper money contains no magnetic materials. Magnets will not attract it, unless you got some candy slime stuck to the magnet.
The other answerer was wrong, a rare earth (neodymium) magnet does indeed attract US paper currency. Try it, I did. There is a slight but definite attraction between a neodymium magnet and a dollar bill - it is likely the metallic compounds in the ink. I don't think you need do much more for your experiment; in this case there is either an attraction or there isn't. Often that is what an experiment is all about - the test either works or it doesn't. You could also test other denominations, a $5, a $10. And find paper money from other countries, is it attracted or not? Also experiment with coins. Older US nickels, and Canadian quarters, can be attracted by strong magnets (it's the nickel metal in the coins).
