Magnetization direction and orientation direction The magnetism of permanent magnets mainly comes from its crystal structure that is easily magnetized. It can obtain extremely high magnetism under the action of a strong external magnetic field, and its magnetism will not disappear after the external magnetic field disappears. Therefore, "magnetization" is NdFeB A key step for [...]
The special metal bond structure of iron cobalt nickel leads to their paramagnetism? Yes, metals such as iron cobalt nickel have special electronic structures that allow them to be strongly magnetic. In these metals, each atom has unpaired electrons in its outer shell that can interact to create magnetism. Such magnetism is called paramagnetism because [...]
How inductive sensors work Inductive sensors are often used to measure position or velocity, especially in harsh environments. The terminology and technology of inductive position sensors can be confusing for many engineers. In this article, the various types of inductive sensors are explained, how they work, and their respective strengths and weaknesses. Inductive position and [...]
Efficient use of weak magnetic energy, new collectors help IoT sensors "self-generate" CHINA's "dual-carbon" strategy advocates a green, environmentally friendly, and low-carbon lifestyle, which depends on the continuous development and innovation of green energy technologies. At the moment when our country is vigorously developing renewable energy, the recovery and reuse of micro-energy such as magnetic [...]
Gold, silver, copper, and iron are all metals. Why do magnets only attract iron? It is a well-known phenomenon that a magnet will attract iron. I believe that everyone has tried to use a magnet to approach other metals to see if the magnet can attract them. However, the "experimental results" are often disappointing. Because [...]
Introduction to the principle of magnet power generation, Free electrons in a conductor are subject to the Lorentz force According to the law of conservation of energy, energy cannot be generated without reason, nor can it disappear without reason. The electric energy generated by magnets must come from other forms of energy. Physics tells us: [...]
How can it be regarded as a valuable strong magnet, and how to distinguish Now many people know that strong magnet is more valuable, but they are not very clear about what kind of strong magnet is, because there are many kinds of magnets, and some people ask whether it is strong magnet if the [...]
If a magnet keeps doing work, will its magnetism be weakened or even disappear? There are many misconceptions about magnets and how they are magnetic. Since the magnetism of a magnet is invisible and intangible, it will be more abstract in the eyes of many people, and it is difficult to reflect it intuitively. First [...]
Magnetic Domains In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. That's why you can magnetize them. See how it works in this tutorial. Electrons are teeny tiny magnets. They have a north and a south pole and spin around an [...]
How are magnets made? More than 20 years of doubts have finally been solved Magnets, we remember deeply when we were young, it is a magical thing. After class, I played a magnet fight in the classroom. Two magnetic fighters each took a magnet and placed it on both sides of the center line at [...]
A girl swallowed toy magnet by mistake, and the doctor took it out smoothly 10 days ago, a 7-year-old girl Jiajia (pseudonym) accidentally put 2 toy magnets into her esophagus while playing with her classmates, and then she vomited and cried uneasy. , and then went to the Second Department of General Surgery of our [...]
Doctor, the child eat magnet, what should I do? "Doctor, the child has eaten the magnet, what should I do?" On the morning of May 18, a mother and child came to the Hengjie Town Health Center in Haishu District of Ningbo City. The 7-year-old child accidentally swallowed the magnet. It turned out that the [...]
What to do if you swallow a magnet If the magnet is swallowed in the stomach, if the general condition is good and there are no related symptoms, it can be temporarily observed; if it cannot be discharged, cathartics can be taken orally, or the foreign body can be removed directly under the endoscope. 1. [...]
Why can't small magnets be put together with big magnets? There is no such requirement, that is to say, this statement is wrong. Farewell and small magnets can be stored together. During their storage, the magnetic attraction force of the large magnet will not be separated from that of the small magnet. The weakening of [...]
Do Magnet Coating Affect Magnet Strength? Some customers ask whether the magnet coating will affect its magnetic strength from time to time? How big is the impact? Let's talk about this topic today. This is indeed an important factor to be considered. Although the distance of one or two millimeters between the magnet and another [...]
High Temperature Can Make Magnets Lose Magnetism Quickly A magnet will lose some magnetism immediately when it encounters a high temperature that exceeds its own tolerance. How much high temperature does it need? This depends on the coercive force of the magnet, which is usually expressed by the letter after the magnet grade, such as [...]
Earth’s Magnetic Field Reversal Earth’s Magnetic Field Reversal Took Three Times Longer Than Thought A new study suggests the last field reversal 773,000 years ago took 22,000 years to occur, which could explain some of the inner workings of our planet’s core。 Earth’s magnetic field is known to flip direction with a somewhat unnerving regularity: [...]
Magnetic Pole Reversal Happens All The (Geologic) Time Scientists understand that Earth's magnetic field has flipped its polarity many times over the millennia. In other words, if you were alive about 800,000 years ago, and facing what we call north with a magnetic compass in your hand, the needle would point to 'south.' This is [...]
What Is Magnetic Reversal? Earth is like a giant magnet in several ways. Not only does it have a magnetic north and south pole that act similarly to the poles on bar magnets, but the planet is surrounded by a strong magnetic field, which is electrically charged and able to interact with magnetized matter. The [...]
How Helpful are Powerful Magnets in Daily Life? With the continuous advancement of technology, the use of powerful magnets is becoming more and more extensive, so where can powerful magnets be used in our daily life? What are the advantages of strong magnets that make many products widely used? HSMAG strong magnet How Helpful [...]
The Great Advantages of NdFeB Magnets in Magnetic Therapy Field Ningbo HSMAG Magnetic Industry Co., Ltd. is mainly engaged in two major parts: 1. Industrial supplies: sintered NdFeB, bonding NdFeB and magnetic components, 2. Civilian supplies: gun magnets, rubber magnets, salvage hooks, rotating hooks , magnetic hooks such as square hooks.

Magnetic Particle Examination Magnetic particle examination (MT) is a very popular, low-cost method to perform nondestructive examination (NDE) of ferromagnetic material. Ferromagnetic is defined in ASME Section V as “a term applied to materials that can be magnetized or strongly attracted by a magnetic field.” MT is an NDE method that checks for surface discontinuities [...]
What does the Magnet N35 Mean? What does the magnet N35 mean? How many Gausses does the magnet N35 generally have? Let's talk about this today. N35 magnet magnet N35 mean N35 is a brand of NdFeB magnet. N refers to NdFeB; N35 N38 N40 N42 N45 N48, etc. It is arranged in [...]
The Relationship Between Electricity and Magnetism Together, these two phenomena form the basis for electromagnetism Electricity and magnetism are separate yet interconnected phenomena associated with the electromagnetic force.
