If you want to make electric 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, current will be generated in the line.

Use this phenomenon to keep the closed line stationary and to rotate the magnet continuously.Let the closed circuit cut the magnetic induction wire emitted by the magnet in a static state, then the circuit 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 windmill to produce for the 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.

But now that it is decided, it can only be done.

The first is the manufacture 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 are all acceptable.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-the ferric oxide (Fe3O4) magnet.

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

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, and the addition method.The two most critical reaction substrates for this method are elemental iron (iron scrap, Fe) and iron oxide (rust powder, Fe2O3)...

...

Taking a deep breath, Li Cha washed his hands, put on a dust mask to prevent powder from entering the mouth and nose, and began 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, 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, Fe3O4 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, the 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 finishing these, Richard did not take a break, 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.

What Richard prepares to make is a lead storage battery, which is the cheapest and most common electric vehicle battery on the modern earth.

The reason for choosing it is on the one hand because the material is easy to collect, on the other hand because of the simple structure, there are only four parts: the positive plate group, the negative plate group, the electrolyte and the container.

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

The first, 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 many 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.

Taking a deep breath, 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 Roman era of modern earth, 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 of a large number of people, which became an important cause of the decline of ancient Rome.

Richard knew this, and did not want to repeat the same mistakes, and did not want to be seriously ill before becoming a sorcerer. Therefore, he had done enough protective work before conducting the experiment.

Wear a dust mask first, then wear a bird's beak mask outside, and put on a tight black protective suit covering all skin, and finally wear gloves made of cow bladder.

After preparing, Li Cha 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.

Put a separator between the positive electrode and the negative electrode 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 then the next step was to set up trivial details such as external wires.

Scattered, until the evening, Richard finally completed all.

"Boom" two soft sounds, put the fabricated lead 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.

After all, it is a hot summer, and even working in the relatively cool palace for the whole afternoon 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.

Frowning, Richard opened the door and walked out of the independent laboratory.
