I've been doing a little more readin on this Natural EMF Meter, and it claims to be able to detect weak DC fields, while ignoring AC. I've played with one myself, and have seen it work. Insomuch as when a person walks about in a room, the needle will go off, seemingly detecting a person's movements. Whether it's actually detecting my movement itself, or the bioelectric field I'm putting off I suppose is up for debate. But the other settings on the meter do seem to do as advertised. Would it be safe to say then, that AC is almost always artificial, while weak DC is mostly natural?

O.K., so how can these meters be able to differentiate between artificial EMF and natural EMF? http://www.trifield.com/EMF_meter.htm http://www.trifield.com/EMF_natural.htm What am I missing here?

I guess I'm primarily concerned with the low frequency area. Would it be safe to assume that an AC EMF field is usually artificial whereas a DC EMF field is usually natural?

One other question. The body also gives off EMF as does the Earth and other biological life forms. What portion of the electromagnetic spectrim do these natural EMF's lie? Also, how can one discern between an artificial EMF and a natural EMF, what properties makes them different?

Thanks very much for your help!

How's this?

So if that kind of EMF is not represented in that graph, would there be another graph that does represent it?

Sorry for being a dolt, I'm trying to wrap my head around these concepts in a Physics for Dummies kind of way. But I'm having a hard time finding 50Hz on this graph: You say it's off the bottom, below Long-Waves? By off the bottom, do you mean to say that it's not represented on the chart?

Can any animals see in the Infrared portion? And are there any animals who can hear infrasonic and ultrasonic wavelengths?

Mains, do you mean a main electrical line? And do you mean 50MHz? Just below VHF in the Radio section?

So that would mean that UV light would break down rhodopsin significantly more, is that right?

O.K., so if I were looking at this graph: What portions would I color in to represent the EMF given off by electrical gear that can be detected by an EMF Meter?

Would you know if there's any case studies on such people that I can read up on?

So UV light retards or prevents rhodopsin from covering the rods, thus creating poor nightvision? Can you explain the effects?

Thanks much for your help!
