notes: label: Description (Brief)
content: Replica of an 1836 magneto generator made by Edward Clarke (1791–1859). A direct current generator consisting of a vertically-mounted, laminated magnet (six plates) and rotating coils set at the open end of the magnet. Rotating coils of wire in a magnetic field are features common to all magneto devices and later used in the design of all electric motors and generators. Similar to Saxton's magneto (2001.3038.04), Clarke's generator appeared, in various forms, in electrical laboratories throughout Europe and the US. The widespread experimental use of magnetos--and the parallel development of electrical telegraphy--raised the issue of developing a common language with which to express the results of research and compare the performance of electrical inventions.
