    • 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.

Webster's Revised Unabridged Dictionary
Galvanic, + -meter,: cf. F. galvanomètre,
Chambers's Twentieth Century Dictionary
From Luigi Galvani, of Bologna, the discoverer (1737-98).

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).
