Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They retain magnetic properties for almost ten years – the loss is just ~1% (according to analyses),
- Neodymium magnets are characterized by remarkably resistant to magnetic field loss caused by magnetic disturbances,
- Thanks to the reflective finish, the coating of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to flexibility in forming and the capacity to modify to individual projects,
- Key role in electronics industry – they find application in computer drives, drive modules, medical equipment, and industrial machines.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. Furthermore, small elements of these products are able to complicate diagnosis medical after entering the body.
- Due to complex production process, their price is relatively high,
Holding force characteristics
Highest magnetic holding force – what affects it?
- on a plate made of structural steel, optimally conducting the magnetic field
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a surface perfectly flat
- with direct contact (no paint)
- for force applied at a right angle (in the magnet axis)
- in neutral thermal conditions
Key elements affecting lifting force
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Base massiveness – too thin plate does not accept the full field, causing part of the power to be escaped into the air.
- Material composition – not every steel reacts the same. High carbon content worsen the attraction effect.
- Base smoothness – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, in contrast under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate lowers the lifting capacity.
Warnings
Threat to navigation
An intense magnetic field interferes with the functioning of compasses in phones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.
This is not a toy
NdFeB magnets are not suitable for play. Eating several magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and necessitates urgent medical intervention.
Medical interference
Patients with a pacemaker should keep an large gap from magnets. The magnetism can stop the functioning of the implant.
Keep away from computers
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Pinching danger
Large magnets can break fingers in a fraction of a second. Never put your hand between two attracting surfaces.
Fragile material
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Avoid contact if allergic
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, avoid direct skin contact or select encased magnets.
Powerful field
Use magnets consciously. Their huge power can shock even professionals. Plan your moves and respect their power.
Permanent damage
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.
Mechanical processing
Dust created during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
