How to use neodymium magnet correctly?
Have you ever thought about what magnets are safe? In this article, you can learn whether the magnet is safe. This includes how they are safe and how dangerous they can be if you do not handle them in the right way.
Is our neodymium magnet safe? Neodymium magnets are very safe to use, as long as you handle them carefully. Magnetic fields are not dangerous to humans at all. However, magnets can damage some electronic devices. For example, televisions, hearing aids, watches, credit cards and computers can be damaged by magnets.
Are you familiar with the safety of magnets? If you do that, that would be great! If you don't, you should continue reading. In this article, we will not only tell you how and why magnets are dangerous, but also introduce some basic skills on how to handle magnets in different situations.
Is our neodymium magnet safe?
Neodymium magnets are completely safe for humans and animals, as long as you handle them carefully. For older children and adults, smaller magnets can be used for daily applications and entertainment.
But please remember that magnets are not toys for children and minors to play with. You should never let them use strong magnets like neodymium magnets alone. First, if they swallow the magnet, they may choke on it.
When handling strong magnets, you should also be careful not to hurt your hands and fingers. Some neodymium magnets are strong enough to cause serious damage to your fingers and/or hands if they are stuck between strong magnets and metal or other magnets.
You should also use electronic equipment with caution. As mentioned earlier, strong magnets such as neodymium magnets can damage some electronic devices. Therefore, you should keep magnets at a safe distance from televisions, credit cards, computers, hearing aids, speakers and similar electronic devices.
Generally speaking, when dealing with neodymium magnets, you should try to follow the following five tips.
When handling large and strong magnets, you should always wear goggles.
Always wear protective gloves when handling large powerful magnets
Neodymium magnets are not toys for children to play with. The magnet is very strong!
Keep the neodymium magnet at least 25 cm away from the electronic equipment.
Keep neodymium magnet very safe and far away from people who have cardiac pacemakers or implantable cardiac defibrillators.
Safe transport of neodymium magnet
If you don't know, magnets can't be transported in envelopes or plastic bags like other goods. And of course you can't put them in the mailbox, and expect everything to be transported as usual.
If you put it in the mailbox, it will only stick to the inside of the mailbox, because they are made of steel!
When transporting strong neodymium magnets, you need to pack them so that they will not attach to steel objects or surfaces.
This can be accomplished by using cardboard boxes and a large number of flexible packaging. The main purpose is to keep the magnet as far away from any steel as possible while reducing the magnetic force.
You can also use something called "goalie". The retainer is a piece of metal that closes the magnetic circuit. You only need to connect the metal to the two poles of the magnet, which will contain the magnetic field. This is a very effective way to reduce the magnetic force of the magnet during transportation.
Neodymium magnet and health
Although magnets are generally safe for people's health, it is important to remember that neodymium magnets may be dangerous for some medical implants (such as cardiac pacemakers). Some people also experience nickel allergy when dealing with certain types of magnets, such as magnets used for jewelry.
If you have a pacemaker or implantable cardiac defibrillator, you need to pay attention to the influence of magnets on them. Strong permanent magnets, such as neodymium magnets, will affect the function of pacemakers and implantable cardiac defibrillators.
The study found that if the daily use of magnets is less than 24 cm from the equipment, it will affect such medical equipment.
As mentioned earlier, neodymium magnets coated with nickel can cause allergic reactions. Most people react to nickel only when they have been exposed to it for a long time.
If you are allergic to nickel or worried that you may be allergic to nickel, you should avoid long-term exposure to nickel. How much nickel exposure a person can handle is very personal, so you should handle it carefully.
Tips for safely handling magnets
Asphyxia/swallowing
Don't let children touch the magnet alone. Children can swallow smaller magnets. If you swallow one or several magnets, they may get stuck in the intestine, which may cause dangerous complications.
Electrical hazard
As you may know, magnets are made of metal and electricity. Do not let children or anyone put the magnet into the power socket. It may cause electric shock.
Watch your fingers
Some magnets, including neodymium magnets, can have very strong magnetic strength. If you do not handle the magnet carefully, you may get your finger stuck between two strong magnets.
Very powerful magnets can even break bones. If you need to handle very large and powerful magnets, it is best to wear protective gloves.
Do not mix magnets and pacemakers
Magnets may affect pacemakers and internal cardiac defibrillators. For example, a pacemaker may enter the test mode and cause the patient to become ill. In addition, the defibrillator may stop working.
Therefore, you must keep such equipment away from magnets. You should also suggest that others do the same.
Heavy things
Overweight and/or defects may cause objects to loosen from the magnet. Heavy objects falling from high places may be very dangerous and cause serious accidents.
You cannot always 100% calculate the indicated adhesion of the magnet. The declared force is usually tested under perfect conditions without any form of interference or defect.
Metal fracture
Magnets made of neodymium can be very fragile, sometimes causing the magnet to crack and/or break into many pieces. These fragments can spread to several meters away
magnetic field
Magnets produce a wide magnetic range, which is not dangerous to humans, but can cause damage to electronic equipment, such as televisions, hearing aids, watches and computers.
To avoid this situation, you need to keep the magnet at a safe distance from such equipment.
fire risk
If the magnet is handled, the dust is relatively easy to ignite. Therefore, if you drill holes in magnets or any other activities that generate magnet dust, please keep the fire within a safe distance.
Allergy
Some types of magnets may contain nickel. Even if they are not coated with nickel, they may still contain nickel. Some people may have allergic reactions when exposed to nickel. You may have experienced this on some jewelry.
Please note that nickel allergy may develop from contact with nickel-plated objects. If you already have nickel allergy, of course, you should avoid contact with it.
