It was the self-taught Englishman William Sturgeon who first invented the electromagnet in 1825, a device which naturally shaped the modern motor. This is an extremely good quality and large early example which conservatively dates to around the 1850s or 1860s. Its size meant it would have been used for public demonstration purposes with the main section bolted upside down to a piece of timber for insulation . When power was applied to the coil the associated hook would have stuck securely to the pillars as if by magic and weights could then be added to the hook to show just how strong this electromagnetic connection really was.
This rare example is offered in very original untouched condition and it is particularly lucky that the associated hook bar has not gone missing. This would be perfect for any public display about the history of electricity and motors. It measures 36 cm high x 30 cm wide and the coiled bars are each about 7.5cm in diameter. Being cast iron this is a very heavy item.
