...issue, pending conferences with representatives of his U. S. shareholders, who own some 60% (nonvoting) of present British G. E. stock. It was for these conferences that Stockholders' Representatives Chadbourne and Swope came to London, and it was their visit to Sir Hugo's offices in Magnet House, Kingsway, that prompted the Standard's headline. Said the reporters, breathless...
First he inspected electrical and magnetic phenomena. Everyone knows, and had known, that they are intimately related. Electricity flowing through a wire coiled around a piece of iron makes that iron magnetic. As a piece of wire passes between the prongs of a horseshoe magnet, an electric current is generated. James Clerk Maxwell showed that the laws of electricity and of magnetism were very much alike. Albert Einstein, in 1905. showed that the forces were different aspects of the same mother force...
Without ado he placed a piece of magnetized cobalt steel on a table and in the air some distance above it placed another similar piece. The upper one remained balanced without mechanical support. His explanation was simple: one end of a magnet is positive, the other negative; with two magnets the positive of one attracts the negative of the other, the positive and negative of one repel the positive and negative of the other; cobalt steel can be so highly magnetized that its repellent power can support a relatively large weight against the pull of gravity...
...Elizabethville in the safe of which was locked the entire diamond output of the Congo for 1917, valued at $10,000,000. The Government of His Belgian Majesty has just employed an Italian deep sea diving firm which proposes to raise the safe by means of a potent submarine magnet...
Inside the box were electro-magnetic fields, actuated (through radio vacuum tubes) by an electric current that alternated at stupendously rapid frequencies. The alternations, as is the case with radio broadcasting waves, were too rapid for human ears to hear. But Professor Theremin, as anyone can do with a heterodyne radio receiving set, put one series of his electro-magnet waves against another series and thereby deadened a sufficient number of the millions of waves speeding silently through the box each second to leave few enough oscillations for audibility. (The highest number of waves that the ordinary human...
