Pros and cons of rare earth magnets.
Strengths
- Their power is durable, and after approximately ten years it drops only by ~1% (theoretically),
- Neodymium magnets are exceptionally resistant to magnetic field loss caused by external field sources,
- In other words, due to the shiny finish of gold, the element gains a professional look,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Possibility of detailed machining and adjusting to concrete conditions,
- Versatile presence in modern industrial fields – they are commonly used in data components, motor assemblies, diagnostic systems, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in compact constructions
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a steel housing, which not only protects them against impacts but also raises 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in producing threads and complex forms in magnets, we propose using cover - magnetic holder.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Magnetic strength at its maximum – what affects it?
- with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
- possessing a thickness of minimum 10 mm to avoid saturation
- with a surface free of scratches
- under conditions of gap-free contact (surface-to-surface)
- under vertical force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Distance (betwixt the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material composition – different alloys reacts the same. High carbon content weaken the interaction with the magnet.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Material brittleness
Neodymium magnets are ceramic materials, which means they are prone to chipping. Impact of two magnets leads to them cracking into shards.
GPS Danger
Be aware: rare earth magnets produce a field that confuses precision electronics. Maintain a safe distance from your phone, device, and navigation systems.
Fire risk
Fire warning: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Heat warning
Avoid heat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, ask us about HT versions (H, SH, UH).
Allergic reactions
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If redness appears, cease handling magnets and use protective gear.
Choking Hazard
NdFeB magnets are not suitable for play. Eating several magnets can lead to them connecting inside the digestive tract, which constitutes a severe health hazard and requires immediate surgery.
Bodily injuries
Large magnets can smash fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.
Powerful field
Handle magnets consciously. Their huge power can shock even experienced users. Stay alert and respect their power.
Threat to electronics
Equipment safety: Strong magnets can damage data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
ICD Warning
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
