is there a way to know the frequency of the earth's magnetic field of my area ?

It has field strength, not frequency.

Field strength is different at every point of Earth.
There are maps about this Field strength distribution.



But probably it breathe at Earth Schumann frequency of about 8Hz.

Cannot comment, your question is not clear to me.

I read in a scientific article that the power line waves 50hz and 60hz have high harmonies that can reach 3 khz for 60 hz and 2.5 khz for 50 hz, that is to say until the fiftieth harmony, I want to know if it was the same case for 8 hz ?

So we are talking about harmonics frequency.

All existing oscillation (eg. sine wave, square wave etc.) are able to produce (passing
trough different existing resonators) harmonics frequencies, which are frequencies that
are integers (whole-numbers) multiple of the fundamental frequency.

Pure sine wave, till not distorted by passing trough different distorting means
(LC tank circuits, amplifiers, measurement means etc) have no harmonics peaks.

Pure sine wave is an ideal oscillation (seeking for harmony with environment).
Universe is full of such ideal sine oscillations. Fundamental EM oscillation of our
planet is one of those ideal oscillations (more known as Schumann frequency).

Problem is, that sine "passing thru" environment, are never ideal surrounding and
distort ideal sine vibrations on different way. Even slightest distorted sine then
produce higher harmonics peaks of its own fundamental frequency.

We can take square wave as an "ideal" distorted sine wave. Square waves
produce a broad spectrum of very pronounced harmonics peaks passing trough
different surrounding means.

We can prove this by observing different forms of oscillation (in frequency domain)
wave presenting devices (so called spectrum analyzers).

What to say about Schumann frequency? It is fundamental EM vibration of our planet.
By origin it is pure (ideal) sine wave of about 8Hz. Passing through different environment
means, this fundamental sine become distorted. As all distorted sine waves, it generate
chains of higher harmonics frequencies. Comparing to fundamental sine of 8Hz those
harmonics signal chains are not significant, but are detectable by using special means.
8Hz fundamental is planetary universal oscillation, harmonics related to those planetary
frequency are mostly local oscillation bonded to local distortion.


Practical question. Does bigger golden vein distort fundamental Schumann frequency?
Answer is Yes, cause bigger golden vein is EM resonator, that resonate at one or more
frequencies out of basic Schumann frequency and this way distort 8Hz fundamental sine.
This is (in comparison to fundamental sine) not significant distortion, but it can be
detectable (at harmonics level) by proper apparatus.

Such apparatus should basically:
- first establish very exact Schumann frequency in time of exploration (fundamental
Earth EM frequency is changeable, cause Earth act as changeable living organism),
- filter out all other disturbing frequencies except (say 15) exact harmonics frequencies
of actual (locally distorted) Schumann frequency (not easy task really),
- follow peak signals of (locally distorted) harmonic over explored terrain and put it
on (2 or 3)-dimensional matrix view.
