　　 If you want to make current, you must understand electromagnetics. In the history of modern earth, on October 17, 1831, Faraday first discovered the phenomenon of electromagnetic induction, and then obtained a method of generating alternating current, which is an important achievement in electromagnetics.

　　 The so-called electromagnetic induction phenomenon is that when a magnet passes through a closed line, there will be current in the line.

　　Using this phenomenon, keep the closed line still and keep rotating the magnet. Let the closed line cut the magnetic induction wire emitted by the magnet in a static state, then the line will continuously generate current, and the mechanical energy is converted into electrical energy, thus becoming a simple generator. This is the knowledge in high school physics textbooks, not very advanced, but some of the trouble is the realization of basic materials and basic parts.

　　If you want this engine to run continuously, it is not possible to rely on manpower. It is inefficient and error-prone. You can only rely on natural resources, either wind or water. Richard chose wind power, so he designed a power generating windmill to make for craftsmen.

　　 But the craftsman can only make some simple parts, such as complex rotors, energy storage equipment, rotating shafts, etc., which must be done by yourself, which is very troublesome. Because of this, I didn't want to do this until the last time.

　　 However, since it is decided, it can only be done.

　　 First of all, the production of the rotor.

　　The main material of the rotor is a magnet, neodymium iron boron magnet, samarium cobalt magnet, aluminum nickel cobalt magnet, iron chromium cobalt magnet will do. However, the current world is in the Blue Lion Kingdom, and there are no magnets of any kind at all. The type you choose to manufacture is the simplest and most common one-ferric oxide (Fe3O4) magnet.

　　To make a ferroferric oxide magnet, you need to get ferroferric oxide.

　　To obtain this material, there are many methods, such as the hydrogen reduction method of α-iron oxide, the slow oxidation method of ferrous hydroxide, the Harber method, the addition method, the alkali addition method, etc., which is the addition method. The two most critical reaction substrates for this method are elemental iron (iron scrap, Fe) and iron oxide (rust powder, Fe2O3)...

　　Take a deep breath, and Richard cleans his hands, puts on a dust mask to prevent powder from entering the mouth and nose, and starts to operate.

　　 First, Richard put iron filings in sulfuric acid. Visible to the naked eye, as soon as it is put in, the beaker immediately emits a large number of bubbles and reacts violently. In the process, ferrous sulfate (FeSO4) will be generated.

After the reaction was completed, Richard started adding caustic soda (NaOH) and iron oxide (Fe2O3). Then heated to 95 ~ 105 ℃, let addition reaction in the solution, and finally produce iron tetroxide.

　　 However, the ferric oxide was not pure at this time, and Richard transferred the solution to a funnel with filter paper to start filtering. After filtration, the filtered solid matter was dried, and then a series of operations were carried out. Finally, it took a lot of effort to finally produce pure ferric oxide.

　　 Then through the magnetization, ferric oxide becomes a real magnet, a piece of black paint. Repeat this step to make a sufficient number of magnets and fix them in a ring-shaped mold, which makes the most important part of the generator-the rotor.

　　After doing this, Richard did not take a rest, and began to make energy storage equipment. After all, the windmill can generate electricity, but the electricity must be stored before it can be used. This requires the use of real rechargeable batteries, not fruit batteries, nor capacitors like Leiden bottles.

　　 Richard is preparing to make lead storage batteries, which are the cheapest and most common electric vehicle batteries on modern earth.

　　 chose it, on the one hand because the material is easy to collect, on the other hand because of the simple structure, only the positive plate group, negative plate group, electrolyte and container four parts.

　　In addition to sulfuric acid as an electrolyte, only one substance or two substances are actually needed:

　　 The first kind, lead, is used to make negative plate groups.

　　 The second kind, the oxide of lead in the air, lead oxide, is used to make the positive electrode group.

　　 In the current medieval world, there may be a lot of things missing, but lead alone is impossible. Because according to the development of modern earth, in more than 2,000 AD, mankind began to extract a lot of metals such as iron, copper, silver and lead.

　　So, with little effort, Richard got enough lead and lead oxide.

　　 took a deep breath, and Li Cha's gaze rose slightly.

　　 Both lead and lead oxide are toxic. Excessive inhalation and ingestion can cause heavy metal poisoning, ranging from physical discomfort to death.

　　In the modern Roman era, the ancient Romans did not know the dangers of lead. Long-term use of lead pipes as water pipelines and lead as a drinking container led to chronic lead poisoning in large numbers of people, which became an important cause of the decline of ancient Rome.

　　Richard knew this and didn't want to repeat the same mistakes, and he didn't want to be seriously ill before becoming a wizard. UU Kanshu www.uukanshu.com therefore did adequate protection work before conducting the experiment.

　　 First put on the dust mask, then put on the beak mask outside, put on a tight black protective clothing that covers all the skin, and finally wear gloves made of cow bladder.

　　After preparing, Richard took a deep breath and felt the air pour into the lungs through the herbal sac in the bird's beak mask, his eyes were fixed, and he started.

　　First, pour enough sulfuric acid into the prepared container as the analysis solution. Then insert the gray velvet lead plate as the negative electrode into the container and fix it. Then put the brown lead oxide plate as the positive electrode and fix it.

　　Place a separator between the positive and negative electrodes to prevent contact between the electrodes. Afterwards, this step is repeated continuously, in which the lead plate and the lead oxide plate are continuously inserted into the container, and finally the entire container that is plugged is full.

　　 The reason for this is to put multiple sets of positive and negative plates into a series to play a role in series, thereby increasing the voltage of the lead battery.

　　After doing this, Licha breathed a sigh of relief, knowing that the main work of the lead battery was completed, and the next step was to set up the external wires and other trivial details.

　　 is scattered, until the evening, Richard finally completed all.

"Boom" two soft sounds, put the fabricated lead-acid battery and rotor on the wooden frame, Richard turned to take off his gloves, took off the beak mask, took off the dust mask, took off the protective clothing, and then found the whole body All soaked.

　　 is a hot summer after all, even in a relatively cool palace, working all afternoon, it is extremely sinful. I didn't notice when I was working. After finishing, Li Cha felt that the underwear was clinging to the skin, and the whole body was very sticky.

　　 frowned, and Richard pushed the door out of the independent laboratory.
