"The Hall effect is a type of electromagnetic effect, a phenomenon discovered by the physicist Hall of the United States of America in 1879 when he was studying the conductive mechanism of metals. Pen ~ Fun ~ Pavilion www.biquge.info"

"When the current passes through the conductor perpendicular to the external magnetic field, the carriers are deflected, and an additional electric field is generated perpendicular to the direction of the current and the magnetic field, resulting in a potential difference between the two ends of the conductor, which is called the [Hall effect], and this potential difference is also called the [Hall potential difference]."

"The birth of the Hall effect is a huge impetus for electromagnetism and electrical industry technology, according to the Hall effect, with a conductive fluid such as air or liquid, and the magnetic field relative to the movement of the current to produce an electric current, in response to the birth of a more environmentally friendly and energy-saving advanced power generation equipment that is [ferrofluid generator], you can also call it [plasma generator]."

"Unfortunately, there are only three countries in the world that have mastered the manufacturing technology of [magnetofluid generator], namely the Soviet Union, the United States of America and the German Confederation, of which the German Confederation has only mastered the first generation of [ferrofluid generator] manufacturing technology, which is limited to experimental applications. The United States of America, on the other hand, announced a breakthrough in super-electromagnetism just five years ago, and by this measure, they are only at the level of the technology of the Soviet Union fifteen years ago, and they are still at least a generation and a half behind it. ”

"Like the amazing achievements of the Soviets in the field of electromagnetism in the past, there is no doubt that the Soviets are once again at the forefront of the world in the field of [magnetofluid generator] manufacturing. All indications indicate that the Soviet Union may well have broken through the constraints of materials, made further progress, and mastered the technology of manufacturing mature equipment for large-scale industrial power generation! ”

The spacious and bright screening room was crowded with people on seats as many as 170 sheets.

On the podium in front of the classroom, an old man with a white beard and a thin but very energetic head was standing on it, waving his teaching stick, and he did not look at the books on the lectern in front of him, but still narrated his knowledge skillfully and coherently.

This old man is Professor Liu Xiaowen, as an authority in the field of electromagnetic in the Ming Dynasty, the old professor has extraordinary popularity in the school, and he is also the only teacher in the school who must attend every class in the screening classroom.

Because any ordinary classroom in the school can't sit so many students.

The long lecture made the old professor's mouth a little dry, and by drinking saliva to moisten his throat, he glanced at the watch time on his wrist, and found that there were only four or five minutes left before the end of the class, and the old man gave up and continued to talk about the rest of the class.

This is also one of his consistent advocates, not to waste a minute of teaching time, nor to delay a minute of rest for students.

It is the strict ethics that have been carried out for decades that have created the noble morality and character of the elderly.

After seeing the old man on the podium close the textbook, many students in the classroom quickly came back to their senses, and tacitly took out their mobile phones and watches to look at the time, and found that after the class was about to end in a few minutes, most of them could not hide their excitement in their eyes.

Sun Cheng was no exception, sitting in the corner of the front row, he immediately stopped whispering to the boss Yang Lin, because the old professor's extracurricular topic time was up.

Sure enough, soon Professor Liu Xiaowen's slightly Xiangxi Chinese sounded in the screening classroom along with the sound microphone on his chest.

“…… When it comes to the world-leading electromagnetic technology of the Soviet Union, I believe many students here will think of the [Two-Day War] a year ago! ”

"As we all know, the Soviet Union was in danger of disintegration in 1991 due to a covert war launched by the NATO bloc against the Soviet Union in the eighties of the last century called "Peaceful Evolution". Although the then Vice President of the Soviet Union, Yanayev, turned the tide and stepped forward in the crisis to launch the [August 19 Coup], executed a large number of politicians, including Yeltsin and **********, and pulled the Soviet Union back from the precipice with an iron fist. However, the [peaceful evolution] still led to the loss of a total of thirteen member states of the Soviet Union, including the three Baltic states, the three Transcaucasian states and the three Central Asian states, and Georgia was one of them! ”

"After Georgia declared independence in 1991 despite Soviet opposition, the Soviets, in retaliation, orchestrated its subordinate autonomous region, South Ossetia, to secede from Georgia at the end of the same year and established itself as a state, and immediately recognized its sovereignty."

"The year before last, the Georgian hawkish politician who was known for his anti-Soviet situation, Irakli, came to power, and because of the support of the NATO bloc, he became increasingly tough on South Ossetia. After careful preparations, Georgia sent troops to quickly storm South Ossetia and occupy its capital, Tskhinvali, last year, and it was reported that NATO fighters had also been present in that offensive. The Soviet Union immediately invoked the military cooperation agreement signed with the South Ossetian government and sent troops into South Ossetia to exchange fire with the Georgian army. ”

"In order to give a fierce response to NATO, an old adversary supported by Georgia, the Soviets not only put in a mechanized brigade equipped with Rhino tanks [T-90], but also sent a battalion of new [Magnetic Storm Tanks] to the battlefield."

"In the battle for Tskhinvali, the capital of South Ossetia, the Soviets' [Magnet Tank] performed amazingly. It not only makes up for the embarrassment of the 'Rhino Tank', a heavy tank with a large size and lack of flexibility, in modern warfare, but also the terrifying arc-shaped electromagnetic waves fired by the two coil guns it is equipped with can not only penetrate the wall and easily hunt the Georgian army and NATO soldiers and snipers who are trying to hide in the shadows, but it can also be used as a combat platform for the Soviet Union's ground electronic warfare, and the Georgian army is equipped with [RM70 multiple rocket launchers], [T-72 tanks] and [Dana wheeled self-propelled guns] In the battle for Tskhinvali, once you are hit by the [Magnetic Storm Tank] or even grazed by electromagnetic waves at close range, you will lose your combat ability due to the complete collapse of the electronics and fire control systems! ”

"The [Magnetic Storm Tank] caused a huge sensation around the world immediately after it was exposed during the Two-Day War, although in terms of cost, the cost of this powerful new tank may be far more than any of today's 'third-generation main battle tanks'. But many countries, including our Ming Dynasty and the NATO bloc, which border the Soviet Union on land, can only open their eyes to the new fears that this raging polar bear has brought to us, because no one knows how many new gadgets are hidden in its vast arsenal of war! ”

"Undoubtedly, as a pioneer in the field of electromagnetism, the Soviets have mastered enough technology to form a technological generation gap with the countries that are struggling to catch up behind! But when we are studying the advanced electromagnetic technology of the Soviet Union, there is a scientist who absolutely cannot get around! He was the Serbian-Soviet inventor, physicist, mechanical engineer, electrical engineer Nikola Tesla! ”

"Although the Jewish physicist Albert Einstein was rated by the Western scientific community as the greatest scientist in the past 100 years, and even a few years ago, the famous space physicist D'Assault in Europe and the United States left a mysterious note with 'Einstein, Sigma Device, and time travel' written on it, which makes the academic community wonder what this deceased scientist was studying in his later years as a consultant at the American Military Research Institute. But I still think that history should put more glory and focus on another great scientist who belonged to the same period as Albert Einstein, Nikola Tesla! ”

"Tesla not only presided over the design of the modern alternating current system, as the most persistent explorer in the field of modern electromagnetism, his various ideas of electromagnetism still amaze the academic community today, and he himself has also conducted in-depth research on the weaponization of electromagnetism."

"There is information that during the Great Depression in the thirties of the last century, Tesla, who was still living in the United States of America at the time, contacted the Springfield Arsenal because of financial constraints and tried to sell him an improved rifle designed by himself with special electromagnetic components to enhance the propulsion at a price of 2,000 dollars."

However, at that time, the United States of America was in the midst of an economic crisis, and the evaluation experts of the arsenal believed that the special structural design of the rifle would lead to an increase in production costs to two hundred dollars, which was far more than ten times that of an ordinary Springfield rifle. Inferior to artillery, less efficient than machine guns, and even inferior to ordinary rifles in terms of rate of fire, the Springfield Arsenal finally judged it to be an out-and-out failure and refused to buy his invention. ”

It is worth mentioning that the Soviet government officials, who were taking advantage of the economic crisis to buy the United States and negotiate with the Springfield Arsenal to introduce a rifle production line, immediately sent someone to contact Tesla when they learned of the news. After ascertaining his talent and ability, he was invited to the Soviet Union despite the opposition of the American government. Tesla was then personally received by Stalin and commissioned to form Moscow University, the Institute of Physical Science and Technology. Since then, the electromagnetic technology of the Soviets has been plugged into a pair of wings, and it is still leading the world. ”

"For more detailed content in this regard, interested students can go to the library to apply to see the 'Taixi Ordnance Outlook - American Chapter' in the 371st issue of the Ordnance Monthly published by the Yongping Ninth Year Military Department. Or through the Internet and other channels, you can inquire about the later management documents of the Springfield Arsenal under the Army, which was lifted by the United States of America in 2004, as well as the history of Moscow University, which are partially recorded. ”

"Okay, that's all for today's lesson, students who have questions are welcome to come to my office at any time to communicate with me, and ...... after class"

With the arrival of the bell after class, Professor Liu Xiaowen on the podium also stopped the lecture on time.

Putting the baton back on the desk, the old professor picked up the teacup and textbook he was carrying, smiled and explained a sentence to a few classmates who seemed to want to ask him something, and then several people quickly walked out of the projection classroom.

A wonderful class is over, and although many of the students who are stranded in the screening room are still a little unsatisfied, the university life is colorful after all, and it will soon be almost over.
