An electric generator (Long ago, a machine that generated electricity was named "dynamo" today's preferred term is "generator".) is a device for converting mechanical energy into electrical energy. The process is based on the relationship between magnetism and electricity.

Faraday's disk dynamo ... This was the principle behind his disk dynamo, which featured a conducting disk spinning in a magnetic field--you may imagine it to be spun up by some belt and pulley, ... Faraday's moving conductor of electricity was solid (e.g. a copper disk), but a circulating fluid can also create such currents.

Build your own low speed dynamo. ... In course of developing The Homebuilt Dynamo, I have often relied on hunches about how electricity "could" be generated and consequently I have spent quite a few years running up blind alleys, many of which in hindsight have seemed a bit ridiculous.

Dynamo Mode ... Since the total resistance through which this E.M.F. causes a current to flow remains the same through the experiment, the quantity of electricity passing through the galvanometer, and therefore the galvanometer deflection, is proportional to this E.M.F. If the observed deflections are plotted as ordinates...

The development of electricity as a motive power was taken up by a host of inventors as early as 1832, ... Henry Wilde's generator of 1866, considered to be "a machine of enormous and unprecedented power," employed a small, shaft–driven Siemens machine to energize the field coils of the larger dynamo. ;

Faraday discovered that a dynamo and a motor are effectively the same thing. Mechanical energy turns a dynamo to produce electricity and electrical energy makes a motor turn to produce mechanical energy. Current that always flows in one direction is called direct current.
