I saw this experiment on another blog. Click here to see it.?During President’s week in the preschool classroom, we had to try this experiment, too.
We put a dollar bill on the floor and slightly folded it in half just enough so one half of the dollar was not laying completely flat on the floor.
We held a magnet close to the corner of the dollar bill but not touching it. The magnet raised the corner of the dollar up so that it then connected.
The reason behind this magnetism: money is printed with magnetic ink to deter counterfeiting.
