The generator generates electricity by rotating the armature rotor in a permanent magnetic field. Two copper rings, a copper ring collector and a commutation connection device are connected to each end of the armature coil. The instrument consists of a base, anchor, pole shoe, magnetic field, brush, hand wheel, load plate, etc. When the handwheel rotates to drive the armature rotor to rotate, current is generated in the coil, causing the LED to emit light. This instrument is used in primary school science to demonstrate the operating principle of the generator and explain that mechanical energy can be converted into electrical energy.
