Shielding Dirty Electricity Ground Current

AI Thread Summary
Using rubber tires as a shield against dirty electricity and magnetic fields is ineffective, as they do not alter electromagnetic fields or static charge accumulation in the area. The discussion highlights the importance of understanding the sources of electric and magnetic fields, such as nearby power lines, and the need for specific measurements with a Gaussmeter. Magnetic shielding typically involves ferrous materials to redirect magnetic fields, rather than insulators like rubber. Participants emphasize the necessity of clarifying the purpose of shielding and the specific concerns prompting the inquiry. Overall, a more effective solution, such as a Faraday cage, is suggested for those seeking to mitigate electromagnetic interference.

TL;DR Summary
Using rubber to shield a small area of land from magnetic fields caused by proximity to electricty.
Would using an insulator like rubber tires partly buried in the ground + partly protruding above the land surface to create a continuous perimeter around a piece of land possibly shield the land inside of it from the accumulation of charge on the surface of the Earth which occurs in the vicinity of electricity sources, and which can be measured with a gaussmeter? My understanding is that it is an accumulation of electrons that spread over the surface of the earth.

You mention ground currents, magnetic fields, accumulation of charge, using a Gaussmeter, etc. These are all pretty different things.

Can you tell us what the source of the electric (or magnetic?) fields is? How close is the source to the ground? What is the purpose of the shielding? Are your worms dying or something?
 
The dirty electricity that is on the surface of the Earth that creates a magnetic field which can be measured with a gaussmeter. The source is electricity - power lines, household electricity - as stated in my original question.

Well I'm still not seeing that in your OP, but whatever.

What is your Gaussmeter reading? Is it AC or DC? Are the powerlines nearby high voltage transmission lines, or the supply lines to your home? What is in the dirt that you want to shield from this magnetic field?

Magnetic shielding involves using ferrous metal pieces to re-route the magnetic field around anything that you want to shield. There is good info at the website below about how magnetic shielding works:

Not really, no. You should respond to @berkeman 's questions. It seems like you may be trying to do something that won't work based on a concern about something that doesn't exist. I'd only add: where did you get your "understanding"? It looks pretty wrong.

Well, without more information from you it's a bit hard to provide you good quality help, but...

No. Half burying rubber tires in the dirt in the shape of a circle around a piece of land will do absolutely zero to change the magnetic fields (or electric fields or any static electric charge accumulation) in the area. It may qualify you for a certain metalic headwear club, or maybe get you written up in the Crop Circle Weekly Gazette, but it certainly will not change anything EM-field-wise on your property.

We really do want to help you with whatever it is that you want to accomplish. If you could start by answering all of the questions I've asked above, and make it clear what your end goal is, that would be great. Thank you.

Actually, one more question -- would these be steel belted radial tires? That might make a difference... :smile:

No, actually I'm serious about this question. Steel is slightly ferrous (not sure how much for steel belted radial tires), and the steel belts could form conductive loops that could act like shorted turns, depending on frequency and other stuff... :smile:

Maybe you should consider a Faraday cage as a shield, rather than tires as insulation, which won't work inside your square. This is a nice one:
