It is important to choose devices with the right magnetic strength to match the specific use, since a weak magnetic force may be not efficient, while an overly powerful one can be difficult to operate.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to immense power, neodymium magnets have the following advantages:

They do not lose power over time. After approximately 10 years, their power decreases by only ~1% (theoretically),
They are highly resistant to demagnetization by external magnetic sources,
In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
They exhibit extremely high magnetic induction on the surface of the magnet,
Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes and sizes, which enhances their versatility in applications.
Significant importance in advanced technologically fields – are used in computer drives, electric motors, medical equipment or other highly developed apparatuses.

Disadvantages of neodymium magnets:

They can break as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
Possible danger arising from small pieces of magnets can be dangerous, when accidentally ingested, which becomes significant in the aspect of protecting young children. It's also worth noting that miniscule components of these magnets have the potential to hinder the diagnostic process in case of swallowing.

Exercise Caution with Neodymium Magnets

Neodymium magnets can become demagnetized at high temperatures.

Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.

The magnet is coated with nickel. Therefore, exercise caution if you have an allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

If the joining of neodymium magnets is not controlled, at that time they may crumble and crack. You can't approach them to each other. At a distance less than 10 cm you should hold them very firmly.

Neodymium magnets are the most powerful magnets ever created, and their power can shock you.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

Neodymium magnets should not be in the vicinity youngest children.

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Keep neodymium magnets away from people with pacemakers.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Magnets made of neodymium are extremely fragile, leading to shattering.

Neodymium magnets are characterized by significant fragility. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.

Keep neodymium magnets away from the wallet, computer, and TV.

Neodymium magnets produce strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Exercise caution!

So that know how strong neodymium magnets are and why they are so dangerous, see the article - Dangerous powerful neodymium magnets.
