Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- Neodymium magnets prove to be remarkably resistant to magnetic field loss caused by external interference,
- In other words, due to the glossy surface of gold, the element gains a professional look,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to the possibility of accurate shaping and adaptation to custom solutions, NdFeB magnets can be produced in a variety of forms and dimensions, which amplifies use scope,
- Wide application in innovative solutions – they find application in hard drives, motor assemblies, diagnostic systems, and industrial machines.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- We recommend cover - magnetic mount, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these products can complicate diagnosis medical in case of swallowing.
- Due to expensive raw materials, their price is higher than average,
Lifting parameters
Maximum magnetic pulling force – what it depends on?
- on a base made of mild steel, perfectly concentrating the magnetic flux
- possessing a thickness of minimum 10 mm to ensure full flux closure
- characterized by smoothness
- with direct contact (without coatings)
- for force applied at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Angle of force application – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and holding force.
- Plate texture – ground elements ensure maximum contact, which increases force. Uneven metal weaken the grip.
- Thermal environment – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate reduces the load capacity.
Safe handling of neodymium magnets
Shattering risk
Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. We recommend safety glasses.
Pacemakers
Warning for patients: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Permanent damage
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.
Handling guide
Be careful. Neodymium magnets act from a distance and snap with massive power, often quicker than you can move away.
Choking Hazard
These products are not toys. Eating several magnets may result in them pinching intestinal walls, which constitutes a critical condition and necessitates urgent medical intervention.
Threat to navigation
A strong magnetic field negatively affects the functioning of magnetometers in phones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.
Pinching danger
Pinching hazard: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Allergy Warning
Certain individuals suffer from a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching may cause an allergic reaction. We recommend use protective gloves.
Dust explosion hazard
Powder generated during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Protect data
Intense magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
