It is not unusual for a modern person to have electricity at home. Thanks to electricity, we can keep warm, cook food, and at night we have light. And, of course, such conveniences have to be paid for by those enterprises that sell energy and, taking advantage of their position, set a favorable price for them. Therefore, over time, many begin to think about alternative energy sources. For example, the use of solar panels is quite common. True, due to the high cost, few people can buy them. A good way to get electricity for free is a generator, for example, a magnetic one. You can assemble such a generator with your own hands. In order for it to create electricity, permanent magnets are needed. They are absolutely safe for the environment and human he alth, and are also an excellent substitute for other methods of generating electrical energy.
Creating a magnetic generator with your own hands is not so difficult. In stores you can find everything you need, namely, the magnets themselves, aluminum rod or steel, copper wires, tubescardboard, flat washers, lumber, iron nails and a drill. But above all, you need self-confidence and a lot of patience. Only in this way will it be possible to bring the work begun to the end. It is also worth deciding in advance on the size of the future generator. It will depend on energy needs.
Of course, having no experience in this matter, it is important to enlist the support of knowledgeable people who can provide quality leadership. But you should not trust everyone in a row or choose it according to the principle "the higher the price - the more valuable the information." Only proven literature will help to achieve success. For example, there are the following recommendations on how to assemble a generator with your own hands. Drill a hole for the axis in the center of the linear magnet and connect the magnet to the axis so that there is a gap between the ends and the magnet can rotate freely. Take two spools (10) and wind each with 1.25 mm diameter wire with enamel insulation. Next, attach the spool to the wooden frame and fasten the spools to the axle one by one. To check the voltage level at the ends of the windings, spin the magnet. If the voltage during rotation of the thread is maximum, you managed to assemble the generator with your own hands! It remains to wind the thread around the axis, connect the light bulb to the terminals. As long as the thread is pulled, the light will be on. Such a generator is good if the electricity is turned off, but you need to charge your phone.
You can use a magnetic generator for a windmill. It is not difficult to create a small wind farm with your own hands by attaching it to the engine axleair propeller. The voltage will depend on how fast the rotor of the motor rotates. To increase this speed, you can use the apiary from the tape recorder and pulleys. In this case, a small pulley must be mounted on the motor axis, and a large one must be mounted on the screw axis. The current in this case will be variable and unsuitable for charging the battery. If you use a simple rectifier, you get direct current. To do this, you need to take 4 semiconductor diodes, connecting them in a bridge circuit. Such a homemade generator can be rotated both with a propeller and by hand.
Thinking about how to make a generator with your own hands, it is important to understand that the resulting product will have some drawbacks. Usually this is a lower durability than industrial designs, insufficient aesthetics and, of course, lower efficiency and increased dimensions. But then you don't have to spend a lot on a factory generator, and you will have satisfaction from the work done!
