Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- Their magnetic field is durable, and after around 10 years it drops only by ~1% (theoretically),
- They retain their magnetic properties even under strong external field,
- A magnet with a shiny silver surface looks better,
- Magnets are distinguished by huge magnetic induction on the active area,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Thanks to freedom in constructing and the capacity to customize to specific needs,
- Fundamental importance in future technologies – they serve a role in hard drives, brushless drives, advanced medical instruments, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in compact constructions
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- NdFeB magnets lose power 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 extremely resistant to heat
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Additionally, small components of these magnets can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Detachment force of the magnet in optimal conditions – what affects it?
- using a base made of high-permeability steel, acting as a circuit closing element
- whose thickness is min. 10 mm
- with a plane cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- under vertical force direction (90-degree angle)
- in stable room temperature
Lifting capacity in practice – influencing factors
- Distance – existence of foreign body (rust, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin steel does not close the flux, causing part of the power to be escaped into the air.
- Steel type – low-carbon steel attracts best. Alloy steels lower magnetic properties and lifting capacity.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Warnings
Do not underestimate power
Handle with care. Rare earth magnets attract from a long distance and snap with massive power, often faster than you can react.
Magnet fragility
Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.
Warning for heart patients
Warning for patients: Powerful magnets disrupt electronics. Maintain minimum 30 cm distance or request help to work with the magnets.
Crushing risk
Mind your fingers. Two large magnets will snap together immediately with a force of massive weight, destroying everything in their path. Be careful!
Electronic hazard
Equipment safety: Neodymium magnets can damage payment cards and sensitive devices (heart implants, hearing aids, mechanical watches).
Heat warning
Keep cool. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).
Combustion hazard
Dust produced during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Do not give to children
NdFeB magnets are not toys. Swallowing multiple magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and requires immediate surgery.
Compass and GPS
Be aware: rare earth magnets generate a field that confuses sensitive sensors. Keep a safe distance from your phone, device, and GPS.
Avoid contact if allergic
Certain individuals experience a hypersensitivity to nickel, which is the standard coating for NdFeB magnets. Extended handling may cause a rash. We suggest use protective gloves.
