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








Hi Folks,   I want to make a = simple=20 Pendulum with  magnets on the end, which swings like a plumb bob = over a=20 ring shaped coil  (dough nut shaped).
 
I think if the magnet was the same = shape and size=20 as the coil, it would neutralize the voltage as it moved.  As it = would be=20 North side down and South side up, so of the same North pole would = stimulate two=20 parts of the coil at the same time. In this case it should=20 be One North and one South.
 
I think if I used two square magnets, = one N pole=20 down and one S pole down, that would work for swinging, say East and = West, but=20 would not create much if it swung North and South.
Perhaps I could use four magnets, N, S, = N,=20 S?
 
I could make the coil square or = round.  =20
 
In this experiment, I need all the = magnets to float=20 above the coil.   How might I arrange the = magnets?
