Magnetic Current [EPUB ebook] 

Following is the result of my two years experiment with magnets at Rock Gate, seventeen miles Southwest from Miami, Florida. Between Twenty-fifth and Twenty-sixth Latitude and Eightieth and Eighty-first Longitude West. The earth itself is a great big magnet. Now I will tell you what magnetic current is. Magnetic current is the same as electric current is a wrong expression. Really it is not one current, they are two currents, one current is composed of North Pole individual magnets in concentrated streams and the other is composed of South Pole individual magnets in concentrated streams, and they are running one stream against the other stream in whirling, screwlike fashion, and with high speed.
