Backyard Detection of Geomagnetic Storms

Introduction The physics of Earth's magnetic field and its interaction with the sun have always fascinated me. I saw an article where NOAA discussed Geomagnetic Ground Currents in North America . The article tickled me and brought out interests I've had for many years.  In my own back yard, how could I measure this? Research Perplexity to the rescue. Here are two links to my research on the topic: My research with Perplexity is at  https://www.perplexity.ai/search/on-this-page-https-spaceweathe-qlEsXujHR3Cr1vJqsVOTJw My Perplexity page on this matter:  https://www.perplexity.ai/page/detecting-geomagnetic-ground-c-SfndxBoeQ8Oiw6_BVkSImA In short, the idea is to plant four 2 meter copper rods at the four corners of my yard. This will be, roughly, a 18 meter square. Each electrode will be connected to a common demarcation point using buried coaxial cable. With four points, I will be able to measure the direction of the magnetic fields. In short, I will be able to discern whe...
