How powerful are neodymium magnets? Can the human body withstand it?

Neodymium magnets are a member of the rare earth magnet family and are the most powerful permanent magnets in the world. They are also known as NdFeB magnets because they are mainly composed of neodymium (Nd), iron (Fe), and boron (B). They are a relatively new invention that has only recently become affordable for everyday use.

Neodymium magnets are graded according to their material. Generally speaking, the higher the grade, the stronger the magnet. If there is no letter after the grade, the magnet is neodymium of standard temperature.

Neodymium magnets are mainly composed of neodymium, iron, and boron. If the magnet is allowed to come into contact with these elements, the iron in the magnet will rust. In order to protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually best to coat the magnet.

There are several options for coatings, but nickel is the most common and often preferred. Our nickel-plated magnets are actually triple nickel-plated, copper, and nickel-plated. This triple coating makes our magnets more durable than the more common single nickel-plated magnets.

Other coating options are zinc, tin, copper, epoxy, silver and gold. Our gold-plated magnets are actually four layers of nickel plating, copper, nickel and one layer of gold on top. Neodymium materials are brittle and easy to break, and the processing effect is not good by conventional methods.

Processing magnets generates heat that, if not carefully controlled, can demagnetize the magnet or even ignite materials that are toxic when burned. It is not recommended to machine magnets. <>

Unlike most other types of magnets, rare earth magnets have a high demagnetization resistance. They do not lose their magnetism around other magnets or when dropped. If you've never touched neodymium magnets before, you'll be amazed at how strong they are.

Neodymium magnets are more than 10 times stronger than the strongest ceramic magnets. If you're currently using a ceramic magnet in your project, you'll probably use a smaller neodymium magnet and greater retention. You can learn about the relative strength of each of our magnets on our magnet summary page.

The surface magnetic fields for each of our stock magnets are also listed on the same page. We also provide a magnet calculator to help you estimate the magnetic force and magnetic field strength of a magnet at any distance. The potential uses of powerful neodymium magnets are limitless!

This magnet can crush objects weighing several tons, and the human body cannot bear it, and I am afraid that the bones will also be crushed.

Its attraction is so powerful that it can squeeze the human body out, and it is a new type of super magnet.

The hazards of neodymium magnets are as follows:

1. Danger to childrenChildren should always supervise children when handling or playing with magnets, and children who may swallow magnets should always stay away from magnets, and it is common to see news that children have eaten magnets. If more than one magnet is swallowed, they can attract each other through the intestinal wall, jamming and squeezing the digestive tract, causing severe swelling that can be life-threatening and require surgery**. It is best to keep all neodymium magnets out of the reach of children.

2. Crush fingers or fractures Larger specifications of magneto-neodymium magnets can crush people's fingers and fractures.

3. Magnetically sensitive items need to keep a safe distance The strength of neodymium magnets is ten times that of ordinary magnets, and a safe distance (at least 20 cm) is maintained between the magnet and all objects that may be damaged by magnetism. Mechanical watches, pacemakers, cathode ray tube displays and televisions, credit cards, disks, and other magnetic storage media such as videotapes are all affected by strong magnets.

Fourth, there is a danger of cracking or chipping Neodymium magnets are very magnetic, put two magnets together, even small magnets, they will attract each other, jump towards each other with great acceleration, and then slam together. This is the most common cause of magnet breakage, and it is possible that one or both magnets can shatter or shatter. Due to the force exerted by the magnet, debris from a magnet collision can fly into a person's eyes at high speeds, so we recommend that you wear goggles when handling multiple neodymium magnets.

Splinters and broken magnets are sharper, so treat them with the same care as broken glass.

5. Influencing cardiac pacemakersThere is a general lack of understanding of how magnets affect cardiac pacemakers. The operation of the pacemaker will be affected by the close proximity of the magnet. Magnets can set the way the pacemaker works and are not suitable for the user of the pacemaker, which may affect their health.

Once the magnet is removed, this change will stop.

Summary. Neodymium magnet is currently unknown in the commercialization of the highest performance magnet, known as the magneto, its magnetic energy product is more than 10 times that of ferrite, can withstand more than 640 times its own weight of the substance, and its magnetic force also has super lethality. For example:

1. The apple was squeezed and deformed little by little under the magnetic force of the neodymium magnet, and finally the whole apple collapsed and disintegrated. 2. When the scientist placed a can of Coke between two magnets, the moment the rubidium magnet drove in, the tube of Coke was flattened by a strong force, and Coke was scattered everywhere. 3. Neodymium magnets can crush objects weighing several tons, and if the experiment is not an apple, but a human body, I am afraid that under the magnetic force of neodymium magnets, even human bones can be easily crushed.

Summary. Hello, is NdFeB good for people? This sentence is very contradictory, weak magnetism is good for people's health, basically 1000gs of magnetism, harmless and beneficial to people, can promote human blood circulation, but it is best not to wear it for a long time.

And strong magnetism is not good for people! It will affect people's heart and brain health! And strong magnetism is also easy to hurt you, such as more than 10000gs of strong magnetism, two together, can break your fingers.

Is NdFeB magnetism really beneficial to the human body?

Hello, I am sorting out the answer for you, please be patient.

Summary. The magnetic field on the surface of the NdFeB magnet is too strong to exceed the coercivity of the ferrite magnet, and when the same pole is close, the ferrite is demagnetized and charged in the opposite direction. In the end, the same pole becomes a different pole, and it attracts each other.

What is the difference between the attraction and repulsion of ordinary magnets and neodymium magnets?

The magnetic field on the surface of the NdFeB magnet is too strong to exceed the coercivity of the ferrite magnet, and when the same pole is close, the ferrite is demagnetized and charged in the opposite direction. In the end, the same pole becomes a different pole, and it attracts each other.

In other words, if you use the n pole of the ferrite close to the n pole of the NdFeB magnet, when you are very close, the n pole of the ferrite becomes the s pole. This occurs because: 1) the magnetic field close to the surface of the NDFEB magnet is very strong, and 2) the coercivity of the ferrite magnet is not very high.

If it is replaced with two pieces of NdFeB or two pieces of ferrite, this will not happen.

Neodymium magnets can pick up 600 820 times more iron.

Ordinary magnets 200 300 degrees also have magnetic force. The neodymium magnet has been demagnetized.

What I'm asking is how many times greater than the phase attraction and repulsion of a neodymium magnet than a normal magnet? Your answer is already there.

The suction power is about 13 times.

What about repulsion? How many times bigger?

3-10 times the magnet.

Is there such a big difference between the force of attraction and the force of repulsion? Is it accurate?

Yes, yes, kiss.

Suction Repulsion Attraction of the same pole Repulsion of the opposite pole Two magnets attract each other To make them repel each other You have to turn your head At that time, the distance, the magnetic field has changed, and of course the force has changed.

The repulsion is just a bit less than the suction.

This kind of magnet.

It is a permanent magnet whose magnetic properties are second only to holmium at absolute zero, and it is also the most commonly used internal rare earth magnet. Appearance.

NdFeB magnets are widely used in electronic products such as hard drives, mobile phones, headphones, and battery-powered tools. In order to avoid corrosion damage, it is necessary to protect the surface of permanent magnet materials, such as gold, nickel, zinc, and tin plating.

The magnetic energy product (BHMAX) is larger than that of samarium cobalt magnets, and it is the substance with the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metals developed the powder metallurgy process.

Everyone should be no stranger to magnets, it has a very strong attraction, it is very useful in daily life, to say the strongest king of magnets, that is neodymium magnet, it is much more powerful than the general magnet, just say that everyone may not believe it, a small group of foreign countries used experiments to prove how terrible neodymium magnets are.

How powerful are neodymium magnets? Put the apple in the middle of it, and the next second it will disappear in an instant.

To put it simply, the suction of NdFeB on iron can reach 640 times its own weight. This is still a single magnet, if you increase the magnetic circuit design, then the suction power is much more than this value.

Hello, strong NdFeB magnets have no adverse effects on the body, but you should pay attention to safety and avoid accidental ingestion.

The role of the magnet:

Therapeutic effect, the magnet is salty and flat; return to the liver and kidney meridians; quality is heavy and subdued; It has the effect of calming the liver and latent yang, brightening the ears and eyes, calming the nerves, and calming the breath; It is mainly used for the treatment of liver and yang dizziness, palpitations, insomnia, dizziness, tinnitus, deafness, kidney deficiency and asthma.

Some substances can be rubbed into magnets, the material is either iron or steel, but not all steels can be made into magnets because they contain their substances, stainless steel cannot act as magnets.

Now let's make a magnet, the magnet and a screwdriver are the materials you need, take the magnet to rub the metal part of the screwdriver, from one end to the other, they rub it repeatedly, you can make a magnetic screwdriver.

Physical role, guide north, attract light and small objects, electromagnets can be used as electromagnetic relays, motors, generators, electroacoustics, magnetic therapy, magnetic levitation, nuclear magnetic resonance.
