Advantages and disadvantages of rare earth magnets.
Strengths
- They retain full power for around 10 years – the drop is just ~1% (according to analyses),
- They have excellent resistance to magnetic field loss due to external magnetic sources,
- In other words, due to the reflective layer of silver, the element gains visual value,
- Magnets exhibit impressive magnetic induction on the active area,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to modularity in constructing and the capacity to adapt to unusual requirements,
- Huge importance in advanced technology sectors – they are used in data components, motor assemblies, diagnostic systems, and industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
- NdFeB magnets demagnetize 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Due to limitations in creating threads and complex shapes in magnets, we propose using cover - magnetic mount.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these products are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- with the use of a yoke made of special test steel, ensuring full magnetic saturation
- with a cross-section no less than 10 mm
- with a plane perfectly flat
- with zero gap (no coatings)
- for force applied at a right angle (pull-off, not shear)
- in neutral thermal conditions
Lifting capacity in real conditions – factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Angle of force application – highest force is reached only during perpendicular pulling. The shear force of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content worsen the attraction effect.
- Surface finish – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was assessed with the use of a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet and the plate reduces the load capacity.
Safe handling of NdFeB magnets
Shattering risk
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets will cause them cracking into small pieces.
Choking Hazard
Always keep magnets away from children. Choking hazard is high, and the effects of magnets connecting inside the body are tragic.
Heat sensitivity
Keep cool. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Bone fractures
Big blocks can smash fingers instantly. Under no circumstances put your hand betwixt two strong magnets.
Health Danger
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Do not drill into magnets
Fire warning: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
GPS and phone interference
Note: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a safe distance from your mobile, tablet, and navigation systems.
Magnetic media
Equipment safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Skin irritation risks
It is widely known that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, refrain from direct skin contact and opt for encased magnets.
Immense force
Before use, read the rules. Sudden snapping can destroy the magnet or injure your hand. Be predictive.
