Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They retain magnetic properties for around 10 years – the drop is just ~1% (in theory),
- Magnets very well resist against demagnetization caused by external fields,
- Thanks to the reflective finish, the surface of nickel, gold, or silver-plated gives an aesthetic appearance,
- Magnets exhibit impressive magnetic induction on the working surface,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Considering the potential of free forming and adaptation to custom projects, NdFeB magnets can be modeled in a wide range of shapes and sizes, which amplifies use scope,
- Key role in advanced technology sectors – they are used in mass storage devices, electric drive systems, medical equipment, and industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating nuts and complex shapes in magnets, we propose using cover - magnetic holder.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. Furthermore, small elements of these devices are able to be problematic in diagnostics medical in case of swallowing.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Maximum lifting force for a neodymium magnet – what affects it?
- with the contact of a sheet made of special test steel, guaranteeing maximum field concentration
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- with direct contact (no coatings)
- under perpendicular application of breakaway force (90-degree angle)
- at temperature room level
Impact of factors on magnetic holding capacity in practice
- Clearance – existence of foreign body (paint, tape, gap) acts as an insulator, which lowers capacity rapidly (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 plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Demagnetization risk
Do not overheat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Material brittleness
Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Physical harm
Large magnets can smash fingers in a fraction of a second. Under no circumstances put your hand betwixt two attracting surfaces.
GPS and phone interference
Be aware: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your phone, device, and GPS.
Pacemakers
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Keep away from children
Absolutely store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets clamping inside the body are life-threatening.
Fire warning
Powder produced during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Do not underestimate power
Be careful. Rare earth magnets attract from a long distance and connect with huge force, often faster than you can react.
Nickel coating and allergies
Some people experience a sensitization to Ni, which is the standard coating for NdFeB magnets. Extended handling may cause dermatitis. We suggest wear safety gloves.
Electronic hazard
Intense magnetic fields can erase data on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.
