How do stud sensors actually sense current, what would cause the effect to propagate across an 8x8 foot surface area and remain strong enough to be detected?
I asked another group "what is happening", now I would like to ask your group "why". This is a question about electrical sensors included on some stud sensors used in home repair to find wiring within walls. The garage for my home was built in 2000, the garage interior is naked particle board directly nailed to wood studs, and the insulation has paper backing (not foil). When using the electrical sensor, most of an entire wall surface shows having current instead of indicating specific wire routes. Other walls in the garage do not show this effect. When I turn off the breaker for the outlets, the current disappears (so the reading is related to current flow, not a bad sensor). What is the effect the sensor is designed to detect, and why might that effect propagate across the surface of one wall and not the (similarly constructed) other walls? Thanks.
