The ideal choice would be neodymium magnets pin for magnetic boards, which are characterized by outstanding strength of [N38] material when used on a magnetic board, and they stand out in terms of both color variety such as black, white, blue, green, orange, purple, red, and different sizes. Our magnetic pieces feature magnets of maximum size in relation to their plastic components, ensuring excellent adhesion. 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 flexible depending on the quantity of units ordered, allowing for favorable wholesale purchases.

Product suggestions

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose their power (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
  • They are exceptionally resistant to demagnetization caused by an external magnetic field,
  • In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an visually attractive appearance,
  • They have very high magnetic induction on the surface of the magnet,
  • Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
  • The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
  • Key role in the industry of new technologies – are utilized in computer drives, electric drive mechanisms, medical apparatus and very advanced devices.

Disadvantages of neodymium magnets:

  • They can break as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
  • Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
  • Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Potential hazard to health from tiny fragments of magnets can be dangerous, if swallowed, which is crucial in the context of children's health. Additionally, tiny parts of these products have the potential to complicate diagnosis in case of swallowing.

Be Cautious with Neodymium Magnets

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.

The magnet is coated with nickel - be careful 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Keep neodymium magnets as far away as possible from 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 the strongest, most remarkable magnets on the planet, and the surprising force between them can surprise you at first.

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.

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

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Neodymium magnets can become demagnetized at high temperatures.

Despite the fact that magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

Neodymium magnetic are highly susceptible to damage, leading to their cracking.

Neodymium magnetic are delicate and will crack 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. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

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

Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can 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.

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

Magnets will bounce and clash together within a radius of several to around 10 cm from each other.
