Shows the conversion of mechanical energy into electrical energy and principle of working of simple AC and DC dynamos. Complete assembly mounted on a base and capable of generating both AC and DC simultaneously as indicated by the glowing of LEDs. A two pole armature is supported on moulded plastic legs on either side and is positioned between two curved steel strips, provided with for DC output and slip rings for AC output, selectable through a toggle switch. Magnetic field provided by a permanent magnet placed on top of curved strips. The complete arrangement operated by a hand drivan wheel with handle..
Features
Hand-cranked operation: The mechanical energy to turn the device is supplied by a hand-driven pulley connected to the armature. Armature: A coil of wire that rotates within the magnetic field. Permanent magnet: Provides the magnetic field, which is cut by the rotating armature wires. Simultaneous AC and DC output: The device is designed to generate both types of current at the same time, which can be visually indicated by separate outputs, often with a toggle switch to select which one to use.
