Faraday discovers the phenomenon of electromagnetic induction.

From 1821 to 1831, Faraday spent 10 years, from the idea to the experiment, the long years, the pain of failure, the hardships of life, Faraday tasted all kinds of bitterness, after countless repeated research experiments, finally discovered the phenomenon of electromagnetic induction.

Discover the fundamentals of generators.

Using this principle, Faraday created the first induction generator in the history of electromagnetism.

But the Frenchman Pixie applied the principle of electromagnetic induction to make the original generator.

Pixi's generator is a wire coil wound around two cores near a U-shaped magnet that can be rotated (rotated by a handwheel and gear), so that it is aligned with the n and s poles of the magnet, respectively, and the coil wire is drawn out. In this way, when the magnet rotates by cranking the handwheel, due to the change in the magnetic field lines, an electric current is generated in the **ring wire.

From the device of this generator, it can be known that every time the magnet rotates half a turn, the pole of the magnet corresponding to the coil changes once, so that the direction of the current also changes once. In order to change this situation and keep the direction of the current constant, Pixie came up with an ingenious solution: two metal pieces separated from each other to form a cylinder were added to the axis of rotation of the magnet, and the two wires led by the coil were in contact with the two metal pieces through the spring plates.

In addition, two wires are used to contact the two metal sheets to draw out the current. This device, called the commutator, was still used in later generators.

Why does the commutator keep the direction of the current constant? This is because the current flows from the coil into the commutator, which rotates with the magnet. When the magnet turns half a turn, the direction of the current in the coil is reversed, and the commutator also turns around for half a turn and turns the direction, so the output current direction is always the same.

Pixi's invention of this generator is the first of its kind in the world, but of course it has its drawbacks. The areas that need to be improved are: first, rotating the magnet is not as convenient and flexible as rotating the coil; Second, the directional current can be obtained through the commutator, but the current strength is still changing. In order to change this situation, people adopt the method of increasing the number of magnets and coils, and slightly staggering the changing currents together, so that the intensity change of the output current is controlled within a certain range.

In the more than 30 years since Pixie invented the generator, although there have been improvements and some new inventions, the results have not been great, and it has never been possible to develop a generator that can output as much current as a battery and can be used for practical purposes.

In the early human society, human beings discovered that friction produces static electricity, but at that time, people did not know the principle of the modular calendar, and could only attribute it to the gods. Until the 17th century,FranklinThe kite experiment was used to prove the existence of electric motion.

The study of electricity began with Franklin, who invented a number of proper terms such as positive electricity, negative electricity, battery, and discharge. And Faraday.

The discovery of electromagnetic induction became the basis of the generator.

Faraday discovered electromagnetic induction in 1931, which in our colloquial parlance is the phenomenon of "magnetism and electricity". When we put a closed circuit into the varying magnetic flux.

In the process, an electric current is generated. Electromagnetic induction is the basis of human electric power, and other power equipment such as generators and transformers are made under the guidance of electromagnetic induction theory.

Throughout Faraday's life, electromagnetic induction was almost his only achievement, but it was the discovery of electromagnetic induction that made Faraday an immortal scientist. Electromagnetic induction provides the basis for the conversion between electromagnets, and it is also a cheap way for humans to obtain electricity, without generators, humans may still be stuck in the age of steam, relying on steam locomotives.

Drives the limbs to search for machines and equipment.

If it's heat, then the resistance is going to be bigger, and then the electrical power is smaller, so I guess it's something else.

That's no problem, but you have to think about it when using electrical appliances to convert electricity into other energy (here light and heat), he must achieve a dynamic balance, otherwise according to your idea, that is, the electric power is small, and the heat will be small, and then the electric power will be large, and it will be hot, and the electric power will be small. No.

And the reason for emitting light is not necessarily heat, light itself is energy. Electrical power is not equal to thermal power.

Volt battery To illustrate, Faraday was not the inventor of the slip bend of the generator, his merit was the electromagnetic sensing of the theory of the socks.

The generator was invented by Gramm.

Faraday is the father of electromagnetism, and the first generator and electric motor were invented by him. It can be said that the electromagnetic model generator and electric motor established by applying his theory of electromagnetism and magnetism. Relying on his theory, from the 60s of the 19th century, in 1866, the German engineer Siemens made a generator, and in 1870, the Belgian Gramm invented the electric motor.

Faraday's "electromagnetic rotation" experiment realized the transformation of electrical energy into mechanical energy, and also realized continuous rotation, becoming the first electric motor in human history.

Yes. Faraday is the father of electromagnetism, and he invented the world's first electric generator and the Nohate's electrically resistant voltive motor. It can be said that the electromagnetic model generator and electric motor established by applying Songchun's electromagnetic theory are used.

Ferrari invented the first generator because he was influenced by Oersted's experiments with the magnetic effect of electric currents.

No, the generator was invented on October 28, 1831 by Faraday, who invented the disc generator at that time.

Michael. Faraday was the first to invent the generator, but Siemens invented the practical generator to make electricity really available for production.

Faraday had taken great pains to discover this influential scientific principle, and he was convinced that it would be possible to use it to build a generator that could actually generate electricity from the oak.

No. 1834 Jacobi, Germany invents the DC engine.

1888 Yugoslav Blind Stove Husband American Tess Xun early pull hair mill chang disguised as an alternating current motor.

On September 23, 1831, Faraday invented the generator.

Dear, the generator was not invented by Ferrari, it is theorist.

Not a hidden chop 1834 Germany Yazao Chang Bi invented the DC dismantling engine 1888 Yugoslav-American Tesla invented the alternating current motor In 1821, the British scientist Faraday first proved that electricity could be converted into rotational motion. The first person to make an electric motor is said to be Jacobi in Germany.

The generator was not invented by Ferrari. The inventor of the generator was Bikxi.

On October 17, 1831, Faraday made the first noise about the phenomenon of electromagnetic induction, and then obtained a method for generating alternating current. On October 28, 1831, Faraday invented the disc generator, which was the first generator created by the sedan man. Due to his great contributions to electromagnetism, the closed bump cavity is known as the "father of electricity" and the "father of alternating current".

No, it was Faraday who discovered electromagnetic induction and laid the foundation for the generation of generators.

On October 28, 1831, Faraday invented the disc generator. This disc generator, although the structure is simple, is the first generator created by man. The old blind motor of the modern world's empty power generation stove started from it.

Generator Inventor: Michael FaradayMichael Faraday was a student and assistant of the famous British chemist David, whose discovery laid the foundation for electromagnetism, and Naisheng was the forerunner of Maxwell. On October 17, 1831, Faraday discovered the phenomenon of electromagnetic induction for the first time, and then obtained a method for generating alternating current.

On October 28, 1831, Faraday invented the disc generator, the first generator created by man. Because of his great contributions to electromagnetism, he was called the "father of electricity" and "the father of alternating current" by Changshan.

You can look at the previous history books and ask the physics teacher, because this is what the physics teacher teaches.

The generator was invented by Faraday, a famous British scientist. Faraday not only invented many machines related to electromagnetism, but also proposed the famous theory of alternating current. In 1831, Faraday succeeded in developing a machine that could generate electric current, that is, a generator, based on his knowledge of electricity.

Faraday is known as the father of electricity to commemorate Faraday's great contributions.

Faraday was a student of David, a great chemist from England, and also served as David's assistant, Faraday learned a lot from David's side, both in chemistry and physics. Faraday also learned a lot about gases during his time as an assistant, and he once immersed himself in experiments, using electric current reactions to obtain gases.

At the same time, Faraday learned about the conversion between electricity and gas by observing the properties of gases and the many reactions between gases and electric currents. Faraday successfully liquefied many kinds of gases through a simple device, and in order to study the relationship between electricity and magnetic fields, Faraday smelted many alloys, and placed them together with glass to study the relationship between metals and magnetic fields, thus discovering the connection between metals and magnetism, and further excavating the close connection between magnetism and electricity, the famous law of alternating current was discovered through such experiments.

No. 1834 Jacobi, Germany invents the DC engine.

1888 Yugoslav-American Tesla invented the alternating current electric motor.

In 1821, the British scientist Faraday was the first to prove that electricity could be converted into rotational motion. The first person to make an electric motor is said to be Jacobi in Germany. He became a simple device around 1834:

In the middle of the two U-shaped electromagnets, a six-arm wheel is installed, and each arm is equipped with two rod-shaped magnets. After the power is applied, the rod magnet and the U-shaped magnet have mutual attraction and repulsion effects, driving the wheel axle to rotate. Later, Jacobi made a large installation.

Installed on a dinghy, powered by 320 denier batteries, the dinghy made its first voyage on the Elbe in 1838 at a speed of only kilometers per hour, and at the same time, Davenport in the United States also succeeded in producing an electric motor to drive a printing press, and printed the American telegraph sentence "Electromagnetic and Mechanical Information". However, these two types of motors do not have much commercial value, and the cost of using batteries as a power source is too high and impractical.

It wasn't until the first practical DC engine came out that electric motors were widely used. In 1870, the Belgian engineer Graham invented the DC generator, which is similar to the electric motor in design. Later, Gramm proved that when an electric current is fed into a DC engine, its rotor rotates like an electric motor.

As a result, this Gramm-type electric motor was manufactured in large quantities. Efficiency is also improving. At the same time, Germany's Siemens took on the task of building better generators and began to work on vehicles powered by electric motors, so Siemens made the world tram.

In 1879, at the Berlin Industrial Exhibition, Siemens' non-smoking tram won a round of applause from the audience. The Siemens electric locomotive was only 3 horsepower at that time, and the electric locomotive tested by Edison, the American inventor, has reached 12-15 horsepower. However, at that time, all motors were DC motors, which were limited to driving trams.

In 1888, the Yugoslav-born American inventor Tesla invented the alternating current electric motor. It is made according to the principle of electromagnetic induction, also known as induction motor, this motor has a simple structure, uses alternating current, no rectification, no spark, so it is widely used in industrial household appliances, AC motors are usually powered by three-phase AC.

In 1902, the Swedish engineer Danielson first proposed the idea of synchronous electric mechanism.

The working principle of synchronous motor is the same as that of induction motor, the rotating magnetic field is generated by the stator, and the rotor winding is powered by DC, and the speed is fixed and unchanged, which is not affected by the load. Synchronous motors are therefore particularly suitable for clocks, record players and tape recorders.

The DC motor is DC excitation, and the wiring method of the excitation winding is different in working characteristics. The starting torque of the series motor is large, suitable for traction and lifting, and the speed of the motor changes little with the size of the load, and can be adjusted, which can be used for fixed speed or speed regulation.

AC commutator motor, that is, an AC motor with a commutator on the rotor. Because it can be used for both AC and DC, it is called AC and DC motors or general motors, and is mostly used in household appliances.
