Subject: Has Any one tried this kind of pendulum ?

I was just looking at this page
It seems to show a horizontal pendulum at the top.
What I was wondering is if you could build a
pendulum with a rod and mass maybe 18 inches
below the pivot or more then extend the rod one inch
ABOVE the fulcrum of crossed rods bearing
then attach maybe a circular super magnet
then on either side of that magnet attached to
the pendulum attach two opposing super magnets
at some adjustable distance either side to
act as a magnetic spring. If you do this
you may be able to totally eliminate the mechanical
spring and the ability to adjust the opposing magnets
will also adjust its period or whatever.
It will not be linear but may allow for greater
dynamic range due to its non linear
magnetic characteristics ??
I do not have the ability to try this out
but maybe one or more of you already have???
