Hi Jill,
I discovered (a few months ago) the rebar in our new construction, well,
wasn't fully thought out ahead of time.
I didn't know about measuring electric fields and effects then.
It Does contribute to the sensitivity issue.
Fortunately, the rebar in the walls, still has external points, to
connect to ground, or test for the difference between grounded and not
grounded.
These are actually the concrete ties that hold the walls during the
pour. The entire rebar structure should be well connected together, even
though only tied together by wire, and connected by pressure.
Some ties provide better connections than others.
It shows up best on a multimeter configured for measuring body voltage.
Standing on the "basement" or ground floor, concrete with rebar in
floor, and rebar in concrete foundation wall.
With wall ungrounded, the reading is 1300 mV AC.
Step up a few inches, onto a stool or couple of 2x6 boards, and the
reading drops to 700 mV.
Attach ground to the rebar with alligator clip.
Standing on floor is 120 mV, step up off floor, drops to 37 mV.
The rebar in the Floor was not intentionally attached to the rebar in
the walls. and I'm not sure it is.
So it is uncertain how grounding the wall is appearing to affect the
floor. So there is still some mystery.
Too bad there is no exposed metal in the floor to attach a ground wire to...
I can't say how it might have any significant Magnetic field. The iron
might have some "solid magnet" aspects, but should not radiate any field.
I would expect it to resonate or re-radiate wireless aspects. Similar
to the recent issues with matress coils, hangers, and glasses.
Anyone else have ideas on this?
