Topic: Not clear (the magnetic?) a field in a room
I work on normal operation, at office...
Something like Quality Department of electronic production, in my room 3 computers (office equipments are not present)
There is an oscillograph.
It is known that if to concern with a finger of a wand of an oscillograph, at sufficient sensitivity of the order of hundreds millivolt he writes frequency 50 - electromagnetic from the electric system on a finger.
Casually concerned today and looked narrowly - the oscillograph ray seemed "dirty", that is a line with a pulsation 50 - very thick.
Such happens, if against low frequency there is higher with smaller pressure.
Twisted the frequency pen... ... Approximately in a big way 30 millivolt is present frequency nearby 30 . (At a choice in 1 division of 20 microseconds in a cell is located somewhere one and a half peak).
And what it for frequency?
Near to me (in meter) three computers... But for the computer it is frequency like very low, and storage work on ggts/hundreds megahertz... The videocard too.
What for a hogwash?
Whence in a room can be on a surface of a human body with frequency about 30 kilohertz?:confused:
