Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- Their power is durable, and after approximately ten years it decreases only by ~1% (theoretically),
- Magnets effectively protect themselves against loss of magnetization caused by external fields,
- The use of an metallic coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets are characterized by impressive magnetic induction on the outer layer,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling functioning at temperatures approaching 230°C and above...
- Due to the potential of accurate forming and customization to unique projects, magnetic components can be produced in a broad palette of shapes and sizes, which amplifies use scope,
- Universal use in modern industrial fields – they find application in HDD drives, drive modules, diagnostic systems, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which enables their usage in miniature devices
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in producing nuts and complicated forms in magnets, we recommend using casing - magnetic mount.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. It is also worth noting that small components of these devices can disrupt the diagnostic process 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
Holding force characteristics
Highest magnetic holding force – what affects it?
- using a base made of mild steel, serving as a magnetic yoke
- whose thickness reaches at least 10 mm
- with a surface cleaned and smooth
- under conditions of gap-free contact (metal-to-metal)
- under axial force vector (90-degree angle)
- at room temperature
Key elements affecting lifting force
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface quality – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Fire warning
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this may cause fire.
Shattering risk
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
GPS and phone interference
Remember: rare earth magnets generate a field that interferes with sensitive sensors. Maintain a safe distance from your phone, tablet, and navigation systems.
Do not overheat magnets
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
Warning for heart patients
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Data carriers
Powerful magnetic fields can destroy records on payment cards, HDDs, and storage devices. Stay away of at least 10 cm.
Bodily injuries
Large magnets can smash fingers in a fraction of a second. Never place your hand betwixt two strong magnets.
Allergic reactions
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and wear gloves.
Choking Hazard
Product intended for adults. Small elements can be swallowed, causing severe trauma. Keep out of reach of children and animals.
Powerful field
Exercise caution. Rare earth magnets act from a distance and connect with massive power, often quicker than you can move away.
