Show The Source of Electricity. Every day the needle of the magnetic mag-netic compass has been observed to sway first one way and then the other upon its pivot with no apparent cause, thus varying from the true meridian of a place. Scientists hava for many years been trying to account for this. Prof. Bigelow has just published his theory of the cause of the disturbance of the magnetic needle. The two magnetic currents, Prof. Bigelow believes, are streaming to us from the sun, one being produced by the corona, tho other coming directly with the sun's rays in straight lines. In other words, according to this theory, electricity is generated by the sun. It reaches us tho same way as sunlight does, and the conclusion is that it is akin to, if not identical with, sunlight itself. The revolving earth is tho gigantic dynamo which excites the electric currents and makes them manifest. This is the summing up of the latest theory as to the source of electricity. There is a certain belief, put forth very anciently, that all matter is one universal substance, manifesting itself in varying forms, according to varying conditions. We seem to be swinging forward to this state of belief again. Practical Electricity. |
