magneto-electrical

A serviceable magneto-electrical machine for giving light is quite expensive.

We might also drive a magneto-electrical machine by a falling weight; it would then furnish electrical currents.

Conversely, by reversing the magnetism in the iron core of the spirals b b, we should obtain in them an electrical current just as we have obtained such currents in the magneto-electrical machine, FIG. 102; in the spirals of that machine there is an iron core which, by being approached to the poles of the large horseshoe magnet, is sometimes magnetised in one and sometimes in the other direction.

But we can attain the same object by mechanical forces, if we produce the electrical current by a magneto-electrical machine.

On the Conservation of Force 1909

Just as the steam engine changes chemical into mechanical force the magneto-electrical machine transforms mechanical force into chemical.

On the Conservation of Force 1909

By an extensive series of experiments with the above apparatus the author succeeded in proving that heat is evolved by the coils of the magneto-electrical machine, as well as by any other part of the circuit, in proportion to the resistance to conduction of the wire and the square of the current; the magneto having, under comparable circumstances, the same calorific power as the voltaic electricity.

In 1840 Wheatstone also brought out his magneto-electrical machine for generating continuous currents, and his chronoscope, for measuring minute intervals of time, which was used in determining the speed of a bullet or the passage of a star.

Weber was also expert in the management of magneto-electrical currents.

It is probable that in this way magneto-electrical arrangements may become very useful in indicating the disturbance of magnetic forces, where other means will not apply; for it is not the whole magnetic power which produces the visible effect, but only the difference due to the disturbing causes.
