Pros as well as cons of Nd2Fe14B magnets.
Pros
- They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
- They feature excellent resistance to magnetism drop as a result of external magnetic sources,
- In other words, due to the reflective finish of nickel, the element is aesthetically pleasing,
- Magnets are characterized by impressive magnetic induction on the working surface,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of accurate machining as well as adjusting to atypical needs,
- Key role in modern technologies – they are commonly used in mass storage devices, electric motors, precision medical tools, and other advanced devices.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
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
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding 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 immune to moisture, in case of application outdoors
- We recommend cover - magnetic mount, due to difficulties in producing threads inside the magnet and complex forms.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Furthermore, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what affects it?
- on a plate made of mild steel, effectively closing the magnetic flux
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a plane free of scratches
- without the slightest clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at room temperature
Lifting capacity in real conditions – factors
- Clearance – the presence of foreign body (paint, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 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 nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Steel type – mild steel attracts best. Alloy steels decrease magnetic permeability and holding force.
- Smoothness – full contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Life threat
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Magnets are brittle
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Avoid contact if allergic
Studies show that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, avoid direct skin contact and opt for versions in plastic housing.
Immense force
Handle magnets with awareness. Their huge power can surprise even professionals. Plan your moves and respect their power.
Danger to the youngest
NdFeB magnets are not intended for children. Swallowing a few magnets may result in them connecting inside the digestive tract, which poses a direct threat to life and requires urgent medical intervention.
Electronic devices
Data protection: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
Combustion hazard
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Precision electronics
Be aware: rare earth magnets produce a field that interferes with sensitive sensors. Maintain a separation from your phone, device, and GPS.
Thermal limits
Do not overheat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Physical harm
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying anything in their path. Exercise extreme caution!
