Iron core tests for NS coil

[IotaYodi]

I received my new 1/2 inch rods today and ran some monitor tests to compare the 3/4 rods I had. The test is nothing but a red background with a large blue circle to test magnetic field intensity. The rods were placed on 5 stacked toroid magnets from microwave ovens for 2 minutes then put up against the monitor screen.

The 1018 had a slightly more intense magnetic field than the A-36. Both were significantly more intense than my unknown hot rolled 3/4 rods. I de- polarized them and repeated the tests 4 times with the same results. I think both these rods would be a better choice than an unknown composition bolt from china. Both are high iron and low carbon for standard rods.

My plans are to make 2 or 3 of these coils for different experiments. I would like to get the silicone alloy 4130 Carbon rod or other silicone rod and try that out also. This wont happen until August or so when Im officially retired.

The more I think about this the more I see NS tapping into a Telluric river. He did say it was pretty precise on a location. Finding the hidden river with a strong current may be a problem. If you did find a strong river you still may have to leave the coil in the ground unloaded until it was charged or primed up enough in order to pump the river. Does anyone think an electrostatic meter could tell if the coil was charged? I wonder if sticking an iron rod into the ground then testing it with an electrostatic meter would work finding a river. I have so many questions and no one to tell me the answers. Lol!
