Subject: How to arrange the magnets?

```Hi Folks,   I want to make a simple Pendulum with  magnets on the end, =
which swings like a plumb bob over a ring shaped coil  (dough nut =
shaped).

I think if the magnet was the same shape and size as the coil, it would =
neutralize the voltage as it moved.  As it would be North side down and =
South side up, so of the same North pole would stimulate two parts of =
the coil at the same time. In this case it should be One North and one =
South.

I think if I used two square magnets, one N pole down and one S pole =
down, that would work for swinging, say East and West, but would not =
create much if it swung North and South.
Perhaps I could use four magnets, N, S, N, S?

I could make the coil square or round.  =20

In this experiment, I need all the magnets to float above the coil.   =
How might I arrange the magnets?

Thanks, Ted
