Invention of 1824

Usage examples of electromagnet.

And such a force-field already exists, even if in weak form, around every natural magnet or electromagnet on earth.

The heavy metals and liquid magma of the inner-core electromagnet are the clutch.

The relux plate was set in a stand directly in front of the projector, and the big electromagnet was set up directly behind the relux plate.

For all I knew I could be flying along with only its electromagnets and a few stray bits of steel clinging to my hull.

When the breaker opens, electrical power to the electromagnets is shut off, the magnets lose their magnetism, and the latches of the rods open, .

SCRAM Breaker--A circuit breaker that interrupts power to the latching electromagnets of the control rod drive mechanisms.

In Germany the Ariston player with thirty-six notes then the Hupfeld with sixty-one still no pneumatics till the Welte family patents its pneumatic Orchestrion operated with a perforated paper roll, in France Carpentier shows his Melograph and Melotrope to the French Academy, mechanical fingers brought to life by electromagnets and a perforated strip.

They went to the trouble of making those bar electromagnets to act on our unipolar field.

How can haphazard nubbiness of grooves pressed into synthetic polymer, read and converted into equivalent electric current, passed through an electromagnet that isomorphically excites speaker paper, sucking it back and forth in a pulsing wave that sets up a sympathetic vibration in thin, skin membrane tickling electrical nerve-bursts simulate not only all the instruments of the orchestra but this most cerebrally self-invested device, the hammer-struck, vibrating string?

The resonant phenomenon produced by the electromagnets can crush the Mil with greater personnel safety, less risk and loss of ships and lives than any improvement in our battle tactics since we refitted the first Star-class ship.

Airtight nanocomposite shells with opposing electromagnets at each end.

So, if you replace the bar magnet with an electromagnet, you can make BIG pulses of electricity.

During the 1830s and 1840s, fresh discoveries included electrolytic refining of a number of metals (principally copper and magnesium), electric arc-lights, improved direct-current motors, and electromagnets.

The diaphragms were connected to a transistorized circuit designed to modulate the field current to the electromagnets.

The metal of the egg's casing was magnetizable, but Gabriel was reluctant to use the electromagnet grapples on the egg in case something inside that casing should react unkindly to a strong magnetic field.
