- noun magnetism produced by an electric current.
- noun one of the fundamental forces of nature, responsible for both electrical and magnetic phenomena. Called also the
electromagnetic force. Formerly believed to be separate phenomena, electricity and magnetism were shown by experiment and theory to be different aspects of the electromagnetic force. It is responsible for the forces generated between magnetically or electrically charged objects, and is the fundamental force responsible for the characteristics of electromagnetic radiation, including light.
- noun the branch of physics concerned with electromagnetic phenomena.

Sorry, no etymologies found.
And when it comes into contact with a suitable metal object, such as a pan of the right material, that electro-magnetism gets translated into heat pretty much instantaneously.
Rosemary had written a new and interesting model for electro-magnetism that she was convinced could be proved empirically by building a circuit that manifested energy efficiencies which defied "conventional" theory ... and that is essentially what has happened: The anomalous energy readings that have been recorded with this circuit defy conventional explanation.
If we are to teach the controversy in this case so to speak then why not do it with all science. moon landing real vs moon landing fake gravity as a separate force, vs gravity as electro-magnetism earth solid vs hollow earth astronomy vs astrology quantum indeterminism vs the natural ontological attitude spherical vs hyperbolic universe
In a recent study, Professor Rustum Roy, Evan Pugh Professor of the Solid State Emeritus at The Pennsylvania State University has demonstrated that crystalline structures can, (if activated via certain forms of electro-magnetism) impart their structure to water.
In their pursuit of a better way to wash clothes, Dyson's researchers tried bombarding them with microwaves, ultrasound and electro-magnetism before settling on the simpler design of the Contrarotator.
An unimaginable cyclone of incandescent gases; an unthinkably huge dynamo pouring its floods of electro-magnetism upon all the circling planets; that solar crater which we now know was, when at its maximum, all of one hundred and fifty thousand miles across; the great sun spot of the summer of 1919 — the most enormous ever recorded by astronomical science.
All those who are thoroughly acquainted with electro-magnetism, and know that it requires measurable time to charge an electro-magnet to saturation
What new achievement of the human mind ought to startle one in this nineteenth century, after having witnessed the wonders of steam and electro-magnetism?
In the same year, and in the three years following, he constructed other electro-magnetic machines and electro-magnets of novel forms; and experimenting with the new apparatus, he obtained results of great importance in the theory of electro-magnetism.
If you earnestly contemplate the important adjuncts to applied science which have sprung from that apparently simple fact, you will not fail to see the importance of the discovery; for it was while working in this new field of electro-magnetism that Sturgeon made the first electro-magnet, and Faraday many of his discoveries relating to induction.
