Pros as well as cons of neodymium magnets.
Pros
- They do not lose magnetism, even over nearly 10 years – the drop in strength is only ~1% (theoretically),
- Neodymium magnets are characterized by highly resistant to magnetic field loss caused by external interference,
- By covering with a reflective layer of nickel, the element acquires an elegant look,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to modularity in shaping and the capacity to adapt to client solutions,
- Wide application in modern technologies – they find application in mass storage devices, drive modules, precision medical tools, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. 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 power 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
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complex forms in magnets, we recommend using a housing - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child safety. Additionally, small components of these magnets can be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets is economically unviable,
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- on a plate made of mild steel, effectively closing the magnetic flux
- possessing a thickness of at least 10 mm to avoid saturation
- with an ground contact surface
- without the slightest clearance between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- at ambient temperature room level
Impact of factors on magnetic holding capacity in practice
- Gap (between the magnet and the plate), since even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, corrosion or dirt).
- Load vector – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped to the other side.
- Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
- Plate texture – smooth surfaces ensure maximum contact, which improves force. Rough surfaces weaken the grip.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was assessed by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet and the plate reduces the load capacity.
Safety rules for work with NdFeB magnets
Threat to electronics
Very strong magnetic fields can erase data on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Permanent damage
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Precision electronics
GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Handling rules
Use magnets with awareness. Their immense force can surprise even experienced users. Be vigilant and respect their power.
Pinching danger
Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!
This is not a toy
Adult use only. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep away from children and animals.
Sensitization to coating
Some people experience a sensitization to Ni, which is the common plating for neodymium magnets. Frequent touching may cause dermatitis. We suggest wear safety gloves.
Magnets are brittle
Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Fire warning
Dust produced during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.
ICD Warning
Individuals with a heart stimulator have to keep an large gap from magnets. The magnetism can interfere with the operation of the implant.
