Magnetic stroke sequence

The word "magnetic" has 14 drawing * *, and the stroke order is: horizontal, left, vertical, horizontal, horizontal, dot, left, left, dot, left, right and dot.

The history of magnetic characters is as follows:

The history of magnetic characters can be traced back to ancient times. In ancient times, people had a certain understanding of the characteristics and applications of magnets. Magnetite is a magnetic natural mineral, which can attract metal substances such as iron. Therefore, people began to make various tools and utensils with magnets, such as compasses and magnets.

In Chinese characters, the origin of the word "magnetic" can be traced back to the ancient word "money". The word "brazing" means "iron" and the magnet is also called "brazing stone", so people combine the word "brazing" with the word "magnetic" to form the current word "magnetic".

With the deepening of people's understanding of magnets, magnetism has gradually become an independent discipline. In ancient times, people began to make compasses with magnets for navigation and military purposes. In modern times, magnetism is widely used in various fields, such as electronics, physics, chemistry and so on.

The history of magnetic characters is closely related to people's understanding and application of magnets. Magnetism has always played an important role, from ancient compasses to modern applications in electronics, physics, chemistry and other fields. At the same time, the word "magnetic" has also become an important vocabulary in Chinese characters, representing human exploration and understanding of nature. The history of magnetic writing can be traced back to China in BC. Ancient magnets were mainly used for divination and medical treatment, and were called "the magic of magnets".

In 1 1 century, the word "magnetism" was first put forward by the Arab scholar Al halliday. In the 3rd century, China scholar Liu An invented the magnetic compass and began to use it in navigation. This invention predates Europe by about 400 years. /kloc-in the 6th century, william Gilbert made a systematic study of magnetism for the first time, and published the monograph Magnets. He found that magnets can attract not only iron but also metals such as steel and nickel. Gilbert also put forward the concept of "magnetic pole".

/kloc-at the beginning of the 8th century, isaac newton studied the magnetic phenomenon and put forward the theory of "Newton's Ring". /kloc-At the beginning of the 9th century, scientists began to study the characteristics of magnetic materials, and found phenomena such as ferromagnetism, diamagnetism and paramagnetism. 1820, hans christian oersted discovered the magnetic effect of current, which laid the foundation of electromagnetism.

At the beginning of the 20th century, scientists such as nikola tesla and Albert Einstein made important contributions to the study of magnetism. Tesla invented the Tesla coil, and Einstein put forward the general theory of relativity, which revealed the relationship between gravity and magnetism. After World War II, the research and application of magnetic materials have developed rapidly.

From 65438 to 0956, American scientist Arno Alper discovered the phenomenon of nuclear magnetic resonance, which laid the foundation of magnetic resonance imaging technology. At the end of the 20th century, scientists also discovered the magnetic monopole, which is expected to bring revolutionary changes to the magnetic energy storage technology.
