Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- They are resistant to demagnetization induced by external field influence,
- A magnet with a shiny silver surface is more attractive,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Due to the potential of precise shaping and adaptation to custom solutions, magnetic components can be created in a broad palette of geometric configurations, which amplifies use scope,
- Wide application in high-tech industry – they find application in mass storage devices, electromotive mechanisms, medical devices, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in miniature devices
Disadvantages
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing nuts and complex forms in magnets, we propose using cover - magnetic mount.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. Additionally, small elements of these products can complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- possessing a thickness of minimum 10 mm to avoid saturation
- characterized by even structure
- with total lack of distance (without coatings)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Distance – existence of any layer (paint, tape, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin plate does not accept the full field, causing part of the power to be escaped to the other side.
- Material composition – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate lowers the load capacity.
This is not a toy
Only for adults. Tiny parts pose a choking risk, leading to severe trauma. Keep out of reach of kids and pets.
Protective goggles
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
GPS and phone interference
An intense magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Keep magnets close to a device to avoid breaking the sensors.
Caution required
Before use, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
Threat to electronics
Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of min. 10 cm.
Heat sensitivity
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.
Finger safety
Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
Fire risk
Machining of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Implant safety
Patients with a heart stimulator should maintain an safe separation from magnets. The magnetism can stop the functioning of the implant.
Allergic reactions
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
