The second pic is a plot produced by the aparatus in pic 1..
although i didnt show the ruler imagine one behind the upper aluminum strip, also you cant see the magnet taped to the bottom of the strip..
the aparatus will still work if i taped the top magnet to the top of the strip..
ok, what i wanted to do was get a plot of the magnetic flux of two magnets taped together both facing the same direction, ie both north poles facing up, needless to say it was not easy , i actually had to use a small strip of copper soldered around the two ..
what i want to do is to use an xy plotter under the upper strip and magnet and take readings of the changing height as the plotter moves .. cool huh?
it should produce a plot as shown in pic 2..
i got the plot by moving the lower two magnets ( not shown) in an x/y fashion and looking at the ruler for the same height, when i found the height i would mark a dot through a hole drilled in the lower plate..
notice how the field looks lopsided ,ie the center part seems to be off to the right a little bit , but thats how it came out...
