    • n galvanometer An instrument for detecting the existence and determining the strength and direction of an electric current. In all galvanometers the principle of action is the same. It depends upon the force which Oersted discovered to be exerted between a magnetic needle and a wire carrying a current—a force which tends to set the needle at right angles to the direction of the current, and whose intensity, other things remaining the same, depends directly upon the strength of the current.

In literature:

The galvanometer is of the Deprez-d'Arsonval type and is extremely sensitive.
"Respiration Calorimeters for Studying the Respiratory Exchange and Energy Transformations of Man" by Francis Gano Benedict
"How Two Boys Made Their Own Electrical Apparatus" by Thomas M. (Thomas Matthew) St. John
The galvanometer is affected like the coils and small magnet in Wheatstone's needle instrument (p. 128).
"How it Works" by Archibald Williams
The galvanometer consists of a magnet set up inside coils through which the current I spoke of flows.
"Astounding Stories of Super-Science, March 1930" by Various
He had me touch an insulated wire to the frost-covered stone from space, while he put the other end to one post of a galvanometer.
"Astounding Stories, March, 1931" by Various
The time marks were made by two galvanometer needles, when successive screens were broken by a shot.
"Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 3" by Various
With alternating currents, however, it is impossible to use a galvanometer in the usual way.
"Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8" by Various
This developed magnetism will re-act upon a coil of wire, and so move a galvanometer needle.
"The Telephone" by A. E. Dolbear
Fortunately the galvanometer absolves you.
"The Social Gangster" by Arthur B. Reeve
A De' Arsonval galvanometer H is also connected to the switch X, so that either the telephone or the galvanometer can be switched in.
"Wireless Transmission of Photographs" by Marcus J. Martin

In poetry:

But with your splendid roundabout
Of mighty power, new-hung and greasy,
With galvanometer so stout,
A new research would be as easy;
A test which might perchance disclose,
Which way the electric current flows.
"Answer To Tait" by James Clerk Maxwell
Take then a coil of copper pure,
And fix it on your whirling table;
Place the electrodes firm and sure
As near the axis as you’re able,
And soon you’ll learn the way to work it,
With galvanometer in circuit.
"Answer To Tait" by James Clerk Maxwell

In news:

Nick Dalacu, of the Niagara Science Museum, 3625 Highland Ave, stands with an Astatic galvanometer circa 1870.

In science:

The history of N-body simulations starts with a pioneering attempt by Holmberg (1941), who followed the evolution of a 37 particle system, where the force was calculated using lightbulbs and galvanometers (taking advantage of the same r−2 scaling of electromagnetic and gravitational interactions).
