EXPERIMENTAL VERIFICATION OF THE CAPACITY OF GENERATING MAGNETISM BY ROTATION OF INCANDESCENT SOLID.

Abstract

A recent scientific publication suggested that geomagnetism has its origins in the inner solid core rotation [1], as shown in Figure 1. This idea is different from the self-excited geodynamo conjecture. This work suggests a way to test if a rotating and incandescent solid body can create magnetic fields and under what conditions. At first, a mathematical analysis looked at the materials and experimental conditions that could be used with low resources. The following materials were identified for the purpose of the experiment: steel, graphite, and tungsten. There were two speeds considered: 1,600 rpm for a common lathe and 9,000 rpm for a bench top wood planer. The two temperatures considered viable were 1350 °C for steel and 2500 ºC for graphite and tungsten. There were two dimensions considered for the rotating part: 50 and 250 mm in diameter and 500 mm in length. In Figure 2, the proposed test circuit is shown. Figure 3 shows the expected result for 50 mm graphite. A double coil of copper wires was constructed to represent the incandescent rotating graphite cylinder, as shown in Figure 4, applying 1 A of dc using a USB charger. Figure 5 shows how the coil magnetism changed from 15 to 15 μm.
