Other offers
Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- Their magnetic field is durable, and after around ten years it decreases only by ~1% (theoretically),
- They feature excellent resistance to weakening of magnetic properties due to external magnetic sources,
- The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to freedom in forming and the capacity to customize to specific needs,
- Wide application in modern technologies – they are commonly used in HDD drives, drive modules, advanced medical instruments, also complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mount, due to difficulties in creating nuts inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices can complicate diagnosis medical after entering the body.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- using a base made of high-permeability steel, functioning as a magnetic yoke
- with a thickness minimum 10 mm
- with a surface perfectly flat
- under conditions of ideal adhesion (metal-to-metal)
- under perpendicular force direction (90-degree angle)
- at standard ambient temperature
Key elements affecting lifting force
- Distance – existence of foreign body (rust, tape, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material composition – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured using a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Safe distance
Device Safety: Strong magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
Allergy Warning
Medical facts indicate that nickel (the usual finish) is a common allergen. For allergy sufferers, prevent direct skin contact and opt for coated magnets.
Heat sensitivity
Avoid heat. Neodymium magnets are susceptible to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Crushing force
Mind your fingers. Two large magnets will snap together instantly with a force of several hundred kilograms, crushing everything in their path. Be careful!
Warning for heart patients
People with a pacemaker must keep an large gap from magnets. The magnetism can disrupt the operation of the implant.
Keep away from children
Adult use only. Small elements pose a choking risk, causing intestinal necrosis. Keep out of reach of children and animals.
Combustion hazard
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Keep away from electronics
Navigation devices and mobile phones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can ruin the sensors in your phone.
Caution required
Handle with care. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can react.
Shattering risk
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets leads to them cracking into small pieces.
