Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
- They maintain their magnetic properties even under strong external field,
- By using a reflective coating of silver, the element has an nice look,
- They show high magnetic induction at the operating surface, which increases their power,
- 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 flexibility in designing and the ability to customize to individual projects,
- Significant place in advanced technology sectors – they serve a role in hard drives, drive modules, medical equipment, as well as technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Limited possibility of creating threads in the magnet and complicated shapes - recommended is cover - magnet mounting.
- Health risk to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Additionally, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- With budget limitations the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum lifting capacity of the magnet – what affects it?
- with the contact of a yoke made of special test steel, guaranteeing full magnetic saturation
- whose thickness equals approx. 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- under axial application of breakaway force (90-degree angle)
- at room temperature
Practical aspects of lifting capacity – factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Load vector – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – too thin steel does not close the flux, causing part of the power to be escaped into the air.
- Metal type – not every steel attracts identically. High carbon content weaken the attraction effect.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
- Thermal environment – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Warnings
Dust is flammable
Powder produced during machining of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Compass and GPS
GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Allergy Warning
It is widely known that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands or select encased magnets.
Implant safety
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Magnets are brittle
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets leads to them shattering into small pieces.
Danger to the youngest
NdFeB magnets are not intended for children. Eating multiple magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.
Thermal limits
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Electronic devices
Avoid bringing magnets near a purse, computer, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Powerful field
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Pinching danger
Protect your hands. Two large magnets will join immediately with a force of massive weight, destroying anything in their path. Exercise extreme caution!
