Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- Their power remains stable, and after around ten years it decreases only by ~1% (according to research),
- Neodymium magnets are characterized by highly resistant to magnetic field loss caused by external magnetic fields,
- A magnet with a metallic gold surface is more attractive,
- The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of individual creating and adapting to precise requirements,
- Fundamental importance in advanced technology sectors – they find application in computer drives, brushless drives, medical equipment, and industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex forms in magnets, we recommend using casing - magnetic mount.
- Possible danger resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that small elements of these magnets can complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Magnetic strength at its maximum – what contributes to it?
- using a plate made of mild steel, serving as a magnetic yoke
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an ground contact surface
- with direct contact (without coatings)
- during pulling in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Gap between surfaces – every millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Load vector – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Metal type – different alloys attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface structure – the more even the surface, the larger the contact zone and stronger the hold. Roughness creates an air distance.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Magnetic interference
A powerful magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Do not bring magnets close to a smartphone to avoid damaging the sensors.
Maximum temperature
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Skin irritation risks
A percentage of the population suffer from a sensitization to nickel, which is the typical protective layer for neodymium magnets. Frequent touching can result in an allergic reaction. We recommend use safety gloves.
Magnet fragility
Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
ICD Warning
Individuals with a ICD must keep an safe separation from magnets. The magnetic field can stop the functioning of the implant.
Physical harm
Large magnets can smash fingers instantly. Do not place your hand between two attracting surfaces.
Safe distance
Avoid bringing magnets near a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Handling guide
Use magnets consciously. Their huge power can shock even experienced users. Be vigilant and respect their force.
Do not drill into magnets
Dust created during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Adults only
Always keep magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are fatal.
