الوصف
It is a cycle dynamo assembly: the dynamo is mounted on a rigid base and is fitted with a crank handle so that the shaft can be turned manually (acting like a bicycle wheel driving it)
Features
Two output terminals (4 mm socket type) are provided for the dynamo’s electrical output. A lamp holder plus lamp (typically a small bulb) is included for visual demonstration of output. The model is commonly used in educational/physics labs (for example under “Electricity / Dynamo” apparatus)
