Advantages as well as disadvantages of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- Magnets effectively defend themselves against loss of magnetization caused by external fields,
- A magnet with a shiny nickel surface is more attractive,
- Magnetic induction on the top side of the magnet turns out to be strong,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
- In view of the potential of free shaping and adaptation to individualized projects, neodymium magnets can be created in a wide range of geometric configurations, which increases their versatility,
- Wide application in modern industrial fields – they are commonly used in hard drives, electromotive mechanisms, medical equipment, as well as modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Limitations
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complicated shapes in magnets, we propose using a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical after entering the body.
- Due to expensive raw materials, their price is relatively high,
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- on a block made of mild steel, optimally conducting the magnetic field
- with a thickness of at least 10 mm
- with a plane free of scratches
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction vertical to the mounting surface
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Clearance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers capacity steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is usually several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Chemical composition of the base – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Adults only
Neodymium magnets are not suitable for play. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and requires urgent medical intervention.
Pacemakers
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Electronic devices
Do not bring magnets near a wallet, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Pinching danger
Mind your fingers. Two powerful magnets will snap together immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!
Nickel coating and allergies
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If redness happens, immediately stop handling magnets and use protective gear.
Fire warning
Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.
Impact on smartphones
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Safe operation
Handle with care. Neodymium magnets attract from a distance and connect with huge force, often quicker than you can react.
Shattering risk
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Maximum temperature
Avoid heat. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
