PDF] Magnetic pulsations in the polar cap ... 21.3 minutes of 3 March is shown with the amplitude in nanotesla per second (nT/s) as a function of frequency, 0 to 50 millihertz. (mHz)
MAGNETORESISTIVE materials are candidates for developing low-power, miniature magnetic field sensors for the detection of sub-nanoTesla magnetic fields at milliHertz frequencies.
Cummings et al. (1969) reported observations of relatively monochromatic magnetic pulsations recorded at synchronous orbit by the magnetometer on ATS 1. These pulsations were largely transverse, had peak-to-peak amplitudes of up to 20 nT, and had frequencies in the range 3-2O mHz. They attributed these pulsations to hydromagnetic resonances in the magnetosphere.
Figure 1a shows the time variations of one horizontal component of the Earth's natural magnetic field, measured with a coil-core magnetometer whose output is the time derivative of the magnetic field, with the scale given in terms of nanoteslas times frequency.

Hilarious. Sounds like New Age bunk. haha.

Oh my. Yeah Persinger really didn't mean millihertz. haha.
How about that magnetometer -- still want to question if it can read nanoTesla at the proper "calibration"? haha.
Sounds like New Age bunk.

I'm going to point out the rather interesting lack of rebuttal in your post.
Essentially, you skirted the actual issue, using the majority of your time to defend yourself and snark at fulllotus.

No, New Age is not bunk. It's stuff that the ancients discovered, and were hidden by various organizations because it meant less reliance upon the system. We're just now giving these things the credence they deserve...it's only "bunk" because we're trained to think the "accepted" way.

Very good find, showing this technology goes back a lot further that people think and consequently is now much farther advanced than they want to admit.

Huh? Your sentence doesn't make any sense.

No, not to you Mary, you don't have the technical knowledge to understand that part in the paper.

I'm glad you have noticed B.S.er blatantly avoiding the difference between frequency and amplitude intensity modulation -- the nanotesla of the magnetometer refers to the amplitude intensity modulation but B.S.er has avoided this issue.
B.S.er first claimed Persinger was using megahertz and B.S.er continues to avoid admitting making this blatant error -- even though it's in the thread.

Intensity www.pemf.com/en/intensity.html Field Intensity (also known as amplitude or flux density)
The determinants of field intensity (amplitude) are the magnetic coil length (meters), the number of turns (or "windings") of the coil, and the strength of the electrical current (Ampères) applied to the coil.

You are lying. I admitted to my confusion regarding the units on page 51.
Just goes to show how brilliant the paper is and how clearly it's all laid out.
amplitude modulated (mHz range) magnetic fields
The amplitude modulation pattern, which contained components and subcomponents within the mHz range, is typical of geomagnetic power densities.
I leave aside the strange fact that Persinger used wrong notation (mHz vs MHz), which actually means "milliHertz". That's a blooper like I haven't seen in a paper.
Few studies have examined EEG outcomes from application of time-varying magnetic fields applied to the whole body with dominant frequencies of 10 Hz or less [25]. One research group conducted two studies [3,4] using the same 1.5 Hz and 10 Hz magnetic fields but applied the fields at two different intensities (100 T vs. 10 T) about a thousand times more intense than the ones employed in the present study.
And again, I'm waiting to see where the "megahertz" signal is coming from, in this setup.
Let me translate the science lingo into English: Persinger's knowledge of lab work is p!ss poor and his paper is worthless.
you never answered how a 7Hz signal modulated in the MHz range can still be considered a 7 Hz signal. Anyone with basic education can tell you that's horsesh!t.
In Persinger's paper, it's a classic word soup and not clear at all, perhaps because they wanted to emphasize the 7Hz part. Funny they didn't mention the exact high frequency they used as a carrier.
But wait, they don't specify what exactly the carrier frequency was. Why? Did you read the paper? If yes, did you see what part of the apparatus was generating the carrier? Did you or did you not? Let me know.
Magnetic flux density B is defined as the force acting per unit current in a wire of unit length at right-angles to the field B = F / ILsin θ → F = B I L sin θ [θ: Angle between the B and L] [NB: write down the above defining equation & define each symbol if you're not able to give the “statement form”.] Direction of the magnetic force is always perpendicular to the plane containing the current I and B [even if θ ≠ 0] The Tesla is defined as the magnetic flux density of a magnetic field that causes a force of one newton to act on a current of one ampere in a wire of length one metre which is perpendicular to the magnetic field.
The results of this experimental simulation of a “sudden commencement” mHz range amplitude modulation of 7 Hz magnetic fields showed that theta activity in the right parietal region was increased for the 20 nT exposures but dampened for the 70 nT intensities compared to sham field controls.

Intensity www.pemf.com/en/intensity.html Field Intensity (also known as amplitude or flux density)
So you could say it's redundant aka synonymous in a magnetic field -- I could have written amplitude intensity flux density. It's not nonsensical. It's the same thing.
The determinants of field intensity (amplitude) are the magnetic coil length (meters)
Oh so Amplitude Intensity is not o.k. yet Amplitude Intensity Modulation is o.k. haha. If you can modulate amplitude intensity then you can write amplitude intensity. So amplitude intensity is sensical.
What about six magnetometers with nanoTesla sensitivity or the nanoteslas of the magnetometers.
