  2. Galvanometer - Wikipedia

    en.wikipedia.org/wiki/Galvanometer

    It is an integrator, by virtue of the long time constant of its response, unlike a current-measuring galvanometer. The moving part has a large moment of inertia that gives it an oscillation period long enough to make the integrated measurement. It can be either of the moving coil or moving magnet type; commonly it is a mirror galvanometer.

  3. Jacques-Arsène d'Arsonval - Wikipedia

    en.wikipedia.org/wiki/Jacques-Arsène_d'Arsonval

    Jacques-Arsène d'Arsonval (8 June 1851 – 31 December 1940) was a French physician, physicist and inventor of the moving-coil D'Arsonval galvanometer and the thermocouple ammeter. D'Arsonval was an important contributor to the emerging field of electrophysiology , the study of the effects of electricity on biological organisms , in the ...

  4. Faraday's law of induction - Wikipedia

    en.wikipedia.org/wiki/Faraday's_law_of_induction

    But when the small coil is moved in or out of the large coil (B), the magnetic flux through the large coil changes, inducing a current which is detected by the galvanometer (G). [ 1 ] Faraday's law of induction (or simply Faraday's law ) is a law of electromagnetism predicting how a magnetic field will interact with an electric circuit to ...

  5. Ballistic galvanometer - Wikipedia

    en.wikipedia.org/wiki/Ballistic_galvanometer

    A ballistic galvanometer is a type of sensitive galvanometer; commonly a mirror galvanometer. Unlike a current-measuring galvanometer, the moving part has a large moment of inertia, thus giving it a long oscillation period. It is really an integrator measuring the quantity of charge discharged through it. It can be either of the moving coil or ...

  7. Mirror galvanometer - Wikipedia

    en.wikipedia.org/wiki/Mirror_galvanometer

    This moving coil galvanometer is mainly used to measure very feeble or low currents of order 10 −9 A. To linearise the magnetic field across the coil throughout the galvanometer's range of movement, the d'Arsonval design of a soft iron cylinder is placed inside the coil without touching it. This gives a consistent radial field, rather than a ...
