Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They do not lose magnetism, even over around ten years – the reduction in strength is only ~1% (according to tests),
- They feature excellent resistance to magnetic field loss as a result of external magnetic sources,
- A magnet with a metallic nickel surface has better aesthetics,
- Neodymium magnets generate maximum magnetic induction on a their surface, which allows for strong attraction,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Considering the potential of flexible forming and customization to individualized solutions, neodymium magnets can be created in a broad palette of geometric configurations, which amplifies use scope,
- Fundamental importance in high-tech industry – they find application in HDD drives, electromotive mechanisms, advanced medical instruments, also technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise 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.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of producing nuts in the magnet and complicated forms - recommended is cover - magnet mounting.
- Health risk 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 small components of these products are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Detachment force of the magnet in optimal conditions – what it depends on?
- with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with a plane cleaned and smooth
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Determinants of practical lifting force of a magnet
- Clearance – existence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures decrease magnetic properties and lifting capacity.
- Surface finish – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Temperature influence – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of optimal thickness, under a perpendicular pulling force, however under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Implant safety
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Combustion hazard
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Phone sensors
GPS units and mobile phones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Fragile material
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. Wear goggles.
Thermal limits
Avoid heat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, look for HT versions (H, SH, UH).
Electronic hazard
Very strong magnetic fields can erase data on payment cards, hard drives, and storage devices. Maintain a gap of min. 10 cm.
No play value
Product intended for adults. Tiny parts pose a choking risk, causing intestinal necrosis. Keep away from kids and pets.
Powerful field
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Be predictive.
Crushing force
Danger of trauma: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Skin irritation risks
Medical facts indicate that nickel (the usual finish) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands or choose versions in plastic housing.
