Pros and cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- They retain their magnetic properties even under strong external field,
- By using a lustrous coating of nickel, the element has an professional look,
- They feature high magnetic induction at the operating surface, which affects their effectiveness,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of detailed modeling as well as modifying to atypical applications,
- Huge importance in future technologies – they find application in data components, drive modules, medical devices, also modern systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose their power 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 durability even at temperatures up to 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 protecting against moisture
- We suggest a housing - magnetic holder, due to difficulties in producing threads inside the magnet and complicated forms.
- Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- using a base made of low-carbon steel, functioning as a magnetic yoke
- whose thickness is min. 10 mm
- characterized by even structure
- with total lack of distance (without impurities)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Base smoothness – the more even the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature influence – hot environment reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a small distance between the magnet’s surface and the plate decreases the holding force.
Warnings
Precision electronics
A powerful magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets near a smartphone to prevent damaging the sensors.
Choking Hazard
Always keep magnets out of reach of children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are life-threatening.
Bodily injuries
Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Nickel coating and allergies
Studies show that the nickel plating (the usual finish) is a common allergen. If your skin reacts to metals, avoid direct skin contact and select coated magnets.
Permanent damage
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Pacemakers
Individuals with a ICD have to maintain an large gap from magnets. The magnetism can interfere with the operation of the life-saving device.
Caution required
Use magnets with awareness. Their huge power can surprise even experienced users. Plan your moves and respect their power.
Keep away from computers
Avoid bringing magnets near a purse, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.
Beware of splinters
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Clashing of two magnets will cause them cracking into shards.
Combustion hazard
Powder produced during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
