Comprising 1 welding coil of 5 turns on former with insulated handle and short-circuiting pins,1 annular melting trough with insulated handle to show heating by induction,1 jumping ring which is thrown clear when primary current is started and a floating ring which remains freely suspended when primary current is flowing.
Wound on rectangular bobbin, for use with 220 – 240 V AC mains with detachable mains connector with moulded plug, A 4 mm socket is provided for earthing.
The dynamo model is mounted on a base with a driving wheel.
Output is through 4 mm sockets and a low voltage bulb is also provided as a simple output indicator.
Enables students to investigate nature and properties of electricity by using simple circuits which are easily constructed on a base board.
The connector system uses P.C.B. strips with cut-out sections whose ends can easily be inserted in spring terminals, ensuring low contact resistance and ease of connection.
