我们的这个手摇发电机的做法非常简单。
该发电机是由一个线圈(约1000转)3厘米,左右一个大钉子,伤口。当纺纱磁铁放在靠近设备上诱导成线圈的电压,这可以被用来点燃灯泡(或最好是一个LED详见年底数) -发电,因此可以简单证明。
The very simple generator described below is primitive but shows the basic operation. It has been deliberately left as simple as possible so that there is maximum scope for using it in imaginative designs and inventi**. It can therefore form the basis for a more complex device as shown a little further on.
The generator is made from a coil of wire (about 1000 turns) wound around the last 3 cm, or so, of a large nail. When a spining magnet is placed near to the device it induces a voltage into the coil and this can then be used to light a bulb (or better still an LED see end for details) - generation of electricity can therefore be simply dem**trated.


Diagram of simple generator
Step 1
Make up two cardboard circles about 3cm in diameter (1-2 mm thick). Carefully pierce a hole in the middle of the circles. Find a large (10-15 cm long, 6 mm wide) clean (unrusty) nail having a large head. Thread one of the circles onto the nail and push right up to the head.
Step 2
Cover the last 3-4 cm of the nail with a single layer of insulation tape (leave the nail head uncovered). Push the second circle onto the nail but only so far as the insulation tape. Add more tape onto the other side of the circle to fix the circle in place. You should now have a ready made 'spool' on which to wind the coil.
