Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their remarkable strength, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after 10 years, the decline in efficiency is only ~1% (in laboratory conditions),
Their ability to resist magnetic interference from external fields is impressive,
The use of a polished gold surface provides a refined finish,
They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
With the right combination of compounds, they reach increased thermal stability, enabling operation at or above 230°C (depending on the design),
The ability for accurate shaping and customization to individual needs – neodymium magnets can be manufactured in multiple variants of geometries, which extends the scope of their use cases,
Important function in advanced technical fields – they are used in HDDs, electromechanical systems, medical equipment and sophisticated instruments,
Thanks to their concentrated strength, small magnets offer high magnetic performance, in miniature format,

Disadvantages of magnetic elements:

They are fragile when subjected to a powerful impact. If the magnets are exposed to shocks, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time enhances its overall durability,
They lose strength at elevated temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the shape and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Magnets exposed to damp air can degrade. Therefore, for outdoor applications, we suggest waterproof types made of plastic,
Limited ability to create threads in the magnet – the use of a external casing is recommended,
Potential hazard linked to microscopic shards may arise, when consumed by mistake, which is important in the family environments. Furthermore, small elements from these magnets have the potential to hinder health screening if inside the body,
Due to the price of neodymium, their cost is above average,

Handle Neodymium Magnets with Caution

Neodymium magnets can become demagnetized at high temperatures.

In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.

Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.

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.

Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.

If have a finger between or on the path of attracting magnets, there may be a serious cut or even a fracture.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

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

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Keep neodymium magnets away from GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

The magnet coating contains nickel, so be cautious if you have a nickel allergy.

Studies show a small percentage of people have allergies to certain metals, including nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Magnets made of neodymium are extremely fragile, leading to their cracking.

Magnets made of neodymium are fragile and will break if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can surprise you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Caution!
