Subject: OmniDirectional Free Hanging Pendulum and Voltage VS Current sensors

Hello All you PSN Peoples;

Please Referr to the following image.
It is much like a product called
Magnasee that allowes one to actually see
the magnetic tracks on a recording tape.
It is referred to as a magnetic developer
sort of like developing an old photography film.
This image is showing a horizontal
EQ motion developer using something
like a kids toy.
Such visualizations will help one understand
the reality of what you are dealing with.

This image from one of your other posts
is a visible indicator that a free hanging
pendulum with a nondirectional sensor
may very well give the best picture
of all X or Y sensors. Otherwise you need
to sum both X + Y with a summation
amp and that will double your effort.

Can someone show me the best way to
use a single simple pendulum with the magnet as
a mass and and one or two coils as the receiver ??

I still like no matter what you say the
magnet as the pendulous mass.

I also know from past experience if you
want to deal with voltages you use vacuum
tubes and if you want to deal with current
you use semiconductors so why do you need
so many coils in a sensor coil ??

Today we use almost always semiconductors
and I think a single loop of very heavy wire
may be better for semiconductors ( IC OP AMPS )
then having multiple turn coils ???

can anyone please address this idea too ??

I am pretty much a laymen but through the
past many years been exposed to many different
general ideas of physics.
