Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- Their magnetic field remains stable, and after around ten years it drops only by ~1% (according to research),
- They have excellent resistance to magnetic field loss due to external magnetic sources,
- The use of an elegant coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Thanks to flexibility in shaping and the capacity to customize to unusual requirements,
- Key role in innovative solutions – they find application in hard drives, motor assemblies, advanced medical instruments, also technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in realizing threads and complicated forms in magnets, we propose using cover - magnetic mount.
- Possible danger related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that small elements of these devices are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- on a plate made of mild steel, perfectly concentrating the magnetic flux
- whose transverse dimension equals approx. 10 mm
- with an ground touching surface
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- in stable room temperature
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or dirt).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is high-permeability steel. Stainless steels may attract less.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Fire warning
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Adults only
Strictly keep magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are fatal.
Demagnetization risk
Do not overheat. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Eye protection
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
GPS and phone interference
Be aware: neodymium magnets generate a field that confuses precision electronics. Keep a safe distance from your phone, device, and navigation systems.
Protect data
Data protection: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, medical aids, timepieces).
Handling rules
Handle magnets with awareness. Their huge power can surprise even professionals. Be vigilant and do not underestimate their force.
Warning for allergy sufferers
A percentage of the population suffer from a contact allergy to nickel, which is the standard coating for neodymium magnets. Prolonged contact may cause an allergic reaction. We recommend wear safety gloves.
Crushing risk
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Health Danger
For implant holders: Powerful magnets affect electronics. Keep minimum 30 cm distance or request help to handle the magnets.
