Currency location of magnetic strip

My grandpa taught me how to do this along time ago and I figured because this is the site that is the depository for all how toing knowledge why not add my own weird trick. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Take American paper currency more than the one one dollar bills do not contain the magnetic strip and hold it up to a bright light. I recommend doing this with five because this may make it so that you can't use the bill in a vending machine or at least it will think its a one.

Strip in U.S. Banknote

This invention relates to a detecting device for detecting a magnetic strip embedded in a sheet such as a check or other currency note. Because of the excellent quality of copies produced by modern copying or printing machines, counterfeit notes, which are difficult to detect, have been easily made using these machines. Countermeasures against such counterfiets have been devised in many countries by embedding a metal strip in the note. A detecting device for automatically discriminating between genuine and counterfeit notes has been developed which detects the existence of the metal strip by utilizing eddy-current loss, as shown in the United Kingdom Patent Application No.

Metal detector knows how much cash is in your wallet

By Jacob Aron. IT HAS long been an urban legend that the security strips found in US banknotes let shadowy government agencies use metal detectors to track how much cash you are carrying. Even though the strips are made of plastic, the legend is so pervasive it once made an appearance in an episode of TV series The X-Files. These inks are already used by vending machines to verify the authenticity of a single note, but physicists Christopher Fuller and Antao Chen at the University of Washington in Seattle realised that large bundles of notes would contain enough magnetic material to be detected at a distance, potentially allowing police to catch people attempting to smuggle cash over the border.
