Induced Current Apparatus P-7950

Induced Current Apparatus P-7950
Used for the study of induced currents, comprises of two solenoids with one smaller of dia to fit in the bigger one. The resistance of the first solenoid is 0.5ohms wound on former 110 x 30 (lxd) and second having resistance of 120 ohms (Approx.) on former 110 x 82mm (lxd). Both the solenoids are prepared with enamelled copper wire and two 4mm socket terminals are mounted on each. Supplied complete with one soft iron core, works on 6-12 V ACDC
