Synopsis

During the 1840s and 1850s, the British government financed a world-wide investigation into how the Earth's magnetic phenomena operated, consisting of a network of naval expeditions and colonial observatories. Questions surrounding terrestrial magnetism were not just philosophical, but engendered urgent concerns over accurate navigation, on which Britain's commercial and colonial power relied.

The British Magnetic Survey was celebrated at the time as the most extensive state-orchestrated scientific enterprise ever conducted. Yet although it was a fundamentally global endeavour, both in terms of its scale and its impact, the experimental instruments and techniques required were to be found amid Britain's booming local industry, where the harnessing of coal and iron, and use of steam power, shaped a scientific culture prominently concerned with the relationship between heat, pressure, and motion. In particular, it was philosophical apparatus fashioned within the mines of Cornwall that the government was able to conscript within this world-wide magnetic investigation. These locally produced experimental techniques and technologies proved capable of transformation into a system for obtaining magnetic measurements from over great expanses of time and space.

As An Empire of Magnetism demonstrates, this not only sustained an immense world-wide scientific investigation, but became inseparable from the proliferation of empire, sustaining colonial expansion and unprecedented multi-cultural exchanges as British naval crews and natural philosophers surveyed previously unknown regions in the search for magnetic data. In so doing, Edward Gillin argues that the British Magnetic Survey had broader implications over the formation of the 'modern state', the expansion of nineteenth-century empire, and the development of global science.
