Hello Charles!

As I said in my posting: 50Hz E-field!

The magnetic fields from a common 60W/230V lamp is very low at distances
of about 1m (a rough guess gives 1-10nT).
As I usually use 60W/24V DC (ripple about 2-3V, I know it is high!)
lamps for reading in my apartment and get less problems from those than
the ones powered directly from 230V, even when the current is about 10
times higher.

The same phenomena (burnt skin), I do get it from cables that are
powered but not necessary carrying any current!

I am quite aware of the physics (real stuff, not "New Age"), so you do
not have to give me any lessons (ash! maybe you can teach me some
english...(;-)).

Regarding Tesla-meters: my personal opinion is that they often is of no
use as they usually gives only RMS-values. I find that the Peek-values
are more interesting.

A Tesla-meter that i would find useful would have the following functions:
- A dynamic range of at least 110dB for each A/D-converter (covering at
least 5nT to 10mT in one range) .
- Simultaneous sampling of all three coils (X,Y,Z).
- FFT-capabilities so i can get a spectrogram with field strength as a
function of the frequency.
- 0-1MHz (divided into 2-5 band).

I guess that I will build one one day...

greetings
