There are formulas for figuring out voltages and turns
and magnetic fields such as design formulas for
transformers since most power today is AC.
But it has been so terribly long ago that I ever
did such things I can no longer tell the technical detales.
Plain Old Physics should have an ideal kind of law
that will answer your questions without being exact
but give you an excellent idea of what to expect.
The internet is the best place to start looking
but out there is some mathematician/physicist that would love
to share his knowledge with you.
Possibly an old Electronics book that deals with such things
as designed for understanding by a layman/noobe.
Mathematicians must account for all units etc. but i think
for a laymen experimentation and curve tracing can
give you good results so long as the goes ins and outs
are close enough for government work.
Simply matching a math curve to the data points found
so you put in the known to get the unknown without
knowing what goes on in the middle.
Magic Numbers and stuff.
(I just wish i knew a few myself)

Subject: How many volts ?


Hi all

I got a coil and magnet from Larry today and I was wondering what the
voltage level of the coil is. But the coil is 9000 ohms.

Regards.
