The best choice would be neodymium magnets pin for magnetic boards, which are characterized by outstanding power of [N38] material when used on a magnetic board, and they stand out in terms of both rich color palette such as black, white, blue, green, orange, purple, red, and different sizes. Our magnetic pieces feature magnets of the largest possible size in relation to their plastic components, ensuring exceptional adhesion strength. The dimensions of the magnets range from smaller ones with an 11 mm diameter to larger ones reaching 29 mm, with heights ranging from 17 mm to 38 mm. Additionally, our pricing policy is diversified depending on the quantity of units ordered, allowing for cost-effective acquisition of larger quantities.

Advantages and disadvantages of neodymium magnets NdFeB.

Besides their stability, neodymium magnets are valued for these benefits:

They do not lose their even during approximately 10 years – the loss of power is only ~1% (based on measurements),
They show superior resistance to demagnetization from external magnetic fields,
In other words, due to the shiny gold coating, the magnet obtains an stylish appearance,
The outer field strength of the magnet shows remarkable magnetic properties,
These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to build),
With the option for tailored forming and precise design, these magnets can be produced in numerous shapes and sizes, greatly improving application potential,
Important function in modern technologies – they find application in HDDs, rotating machines, healthcare devices along with technologically developed systems,
Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of NdFeB magnets:

They are prone to breaking when subjected to a strong impact. If the magnets are exposed to mechanical hits, we recommend in a metal holder. The steel housing, in the form of a holder, protects the magnet from breakage , and at the same time enhances its overall robustness,
Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
They rust in a damp environment, especially when used outside, we recommend using encapsulated magnets, such as those made of rubber,
Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing threads directly in the magnet,
Safety concern related to magnet particles may arise, when consumed by mistake, which is significant in the health of young users. Additionally, tiny components from these products might disrupt scanning if inside the body,
Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications

Caution with Neodymium Magnets

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

The magnet is coated with nickel. Therefore, exercise caution if you have an 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

You should keep neodymium magnets at a safe distance 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, etc. devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Avoid bringing neodymium magnets close to a phone or GPS.

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.

Magnets are not toys, youngest should not play with them.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

Neodymium magnetic are noted for being fragile, which can cause them to crumble.

Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

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

To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Neodymium magnets can become demagnetized at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.

If joining of neodymium magnets is not controlled, at that time they may crumble and crack. Remember not to approach them to each other or have them firmly in hands at a distance less than 10 cm.

Be careful!
