Word History and Origins

Origin of remanent magnetism¹

First recorded in 1865–70

Example Sentences

Under such circumstances, if we suppose the shell, as well as the core, to be of soft iron, we shall obtain a feeble current due to the presence of remanent magnetism; but this magnetism will not be able to continue increasing under the influence of the current.

From Project Gutenberg

It results from this arrangement that, under the action of the current, the polarity due to remanent magnetism does nothing but increase.

From Project Gutenberg

It suffices then for but little remanent magnetism to prime the machine; the polarity of the shell continues to increase, and the energy of the magnetic field, and consequently of the current, has for a limit only the saturation of the soft iron.
