Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- They feature excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
- In other words, due to the aesthetic surface of silver, the element is aesthetically pleasing,
- Magnetic induction on the surface of the magnet is maximum,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- In view of the potential of precise molding and adaptation to specialized projects, magnetic components can be manufactured in a variety of geometric configurations, which expands the range of possible applications,
- Versatile presence in advanced technology sectors – they find application in mass storage devices, motor assemblies, advanced medical instruments, and multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic holder, due to difficulties in realizing threads inside the magnet and complicated 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. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose thickness is min. 10 mm
- characterized by smoothness
- with direct contact (no impurities)
- under axial application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Gap (between the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Metal type – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Protect data
Do not bring magnets near a purse, computer, or TV. The magnetic field can destroy these devices and wipe information from cards.
Shattering risk
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Danger to pacemakers
People with a heart stimulator should keep an absolute distance from magnets. The magnetism can interfere with the operation of the life-saving device.
Flammability
Machining of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Do not give to children
These products are not toys. Eating several magnets may result in them attracting across intestines, which constitutes a severe health hazard and necessitates immediate surgery.
GPS and phone interference
Note: rare earth magnets produce a field that disrupts precision electronics. Maintain a separation from your mobile, tablet, and GPS.
Pinching danger
Big blocks can crush fingers instantly. Never put your hand between two attracting surfaces.
Caution required
Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and respect their force.
Skin irritation risks
Certain individuals experience a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact can result in a rash. We suggest use safety gloves.
Maximum temperature
Standard neodymium magnets (N-type) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
