Everything, therefore, takes place as if, by the fact of electrification, its capacity for kinetic energy and its material mass had been increased by a certain constant quantity. To the ordinary mass may be added, if you will, an electromagnetic mass.
The phenomena are looked upon as due to mechanical deformations or to movements governed by certain forces. The electromagnetic theory leads, as we have seen, to the employment of other images. M.H. Poincaré, and, after him, Helmholtz, have both proposed electromagnetic theories of dispersion.
Suppose water power to be employed to give motion to a dynamo-electrical machine, a very powerful electrical current will be the result, which may be carried to a great distance, through a large metallic conductor, and then be made to impart motion to electromagnetic engines, to ignite the carbon points of electric lamps, or to effect the separation of metals from their combinations.
It might be advisable, in a strictly scientific investigation, when accuracy is of great importance, to do away with the metal cover, as it might introduce many errors, principally on account of its complex action upon the coil, as a condenser of very small capacity and as an electrostatic and electromagnetic screen.
All the experiments effected on the conductivity of gases or metals, and on the radiations of active bodies, have induced us to regard the atom as being constituted by a positively charged centre having practically the same magnitude as the atom itself, round which the electrons gravitate; and it might evidently be supposed that this positive centre itself preserves the fundamental characteristics of matter, and that it is the electrons alone which no longer possess any but electromagnetic mass.
The resulting formulae are those for the electromagnetic theory of relativity, or, as it is now termed, the restricted theory.
While the principal object of this invention was to accomplish the repetition of signals without the aid of an electromagnetic relay, the instrument devised by Edison was capable of use as a recorder also, by employing a small wheel inked by a fountain wheel and attached to the vibrating arm through suitable mechanism.
The engineer also noted that it was possible that the device might be capable of radiation effects outside of the electromagnetic spectrum, and that the power device was capable of integration into standard equipment in fact, might be well worth adoption. He carefully declined, however, to give any definite opinion without an actual model to run tests on.
To increase the positive electromagnetic energies in the organism. To increase the amount of oxygen and ozone in the system and thereby to promote the oxidation and combustion of effete matter. The above-mentioned objects can be attained most effectually by the simple cold water treatment.
Devoting every spare moment to the pursuit of his object, which was attained but slowly by reason of his lack of mechanical skill and ingenuity, not until 1837 had he so far succeeded in his efforts as to be prepared to make application for letters-patent to enable him to secure and protect his rights of invention in the electromagnetic telegraph.
