Well I bough the gaussmeter and in fact the substation didn’t show anything important. But , infront of my house those light poles showed until 4.6 nT almost all that block is like that, only changes when I get closer to my door house it comes until .9 nT but I’ll go inside the house today to check.
Please give me some comments.
Use lots of tinfoil.
Seriously this is far beyond the scope of a home inspection not too mention junk science.
Do you know that the earth’s magnetic field produces 5.0 nT?
The power lines in front of the house is a 3phase feed. You can expect higher readings there.
