Other offers
Strengths and weaknesses of neodymium magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Magnets effectively defend themselves against demagnetization caused by foreign field sources,
- Thanks to the elegant finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an elegant appearance,
- They show high magnetic induction at the operating surface, making them more effective,
- 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...
- Thanks to versatility in shaping and the ability to modify to individual projects,
- Significant place in innovative solutions – they find application in hard drives, motor assemblies, advanced medical instruments, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions
Disadvantages
- To avoid cracks under impact, we suggest using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
- 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- We recommend casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that tiny parts of these devices are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Best holding force of the magnet in ideal parameters – what affects it?
- using a sheet made of high-permeability steel, functioning as a magnetic yoke
- possessing a thickness of at least 10 mm to avoid saturation
- with a plane perfectly flat
- with total lack of distance (without impurities)
- during detachment in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Clearance – the presence of foreign body (paint, dirt, gap) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Material composition – different alloys reacts the same. High carbon content worsen the interaction with the magnet.
- Surface quality – the more even the plate, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Implant safety
Warning for patients: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to handle the magnets.
Electronic devices
Data protection: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Shattering risk
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
Operating temperature
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
Avoid contact if allergic
A percentage of the population suffer from a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact can result in a rash. We suggest use protective gloves.
Handling rules
Handle magnets with awareness. Their immense force can shock even professionals. Be vigilant and do not underestimate their power.
Impact on smartphones
GPS units and mobile phones are highly sensitive to magnetism. Close proximity with a strong magnet can ruin the sensors in your phone.
Dust explosion hazard
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Crushing force
Risk of injury: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Keep away from children
Product intended for adults. Tiny parts pose a choking risk, leading to severe trauma. Keep away from children and animals.
