created by current in a wire could be ‘multiplied’ by coiling the wire. He coiled wire around a wooden rectangular frame and placed a compass needle in the center. By the fall of 1820 (just months after Ørsted’s paper appeared), Schweigger constructed his ‘Multiplier Galvanometer,’ also called ‘Schweigger’s Multiplier.’ In September of 1820, Schweigger presented his findings at the University of Halle (where he was also a teacher). Soon after, his paper was published in the German Literary Gazette, eventually showing up on the desk of every academic physics researcher in Europe.
This image illustrates the simple demonstration performed by Ørsted that initiated the modern age.
As the discovery traveled Europe…
In Bavaria…
In the Summer of 1820, Johann Schweigger was sitting at his desk when the Dutch journal that first published Ørsted’s discovery came in the post. Schweigger was the editor and publisher of the German scientific journal ‘ Journal für Chemie und Physik ’ (often known simply as ‘Schweigger's Journal’). He was uniquely positioned to be one of the first in the world to learn about new scientific discoveries. Recognizing the significance of Ørsted’s experiment, Schweigger immediately saw the potential to measure electric currents with precision. Schweigger first determined that the fields
