Pros as well as cons of rare earth magnets.
Advantages
- They do not lose magnetism, even during approximately ten years – the drop in power is only ~1% (according to tests),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- Thanks to the elegant finish, the coating of nickel, gold-plated, or silver gives an clean appearance,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which allows for strong attraction,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to the option of flexible molding and adaptation to individualized solutions, NdFeB magnets can be manufactured in a wide range of shapes and sizes, which expands the range of possible applications,
- Versatile presence in advanced technology sectors – they serve a role in mass storage devices, drive modules, diagnostic systems, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in compact constructions
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest 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 magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- We suggest cover - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these products can complicate diagnosis medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- using a sheet made of high-permeability steel, acting as a magnetic yoke
- with a cross-section no less than 10 mm
- with a plane free of scratches
- under conditions of ideal adhesion (surface-to-surface)
- during detachment in a direction vertical to the mounting surface
- at room temperature
Practical aspects of lifting capacity – factors
- Distance – existence of any layer (paint, dirt, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Plate material – mild steel gives the best results. Alloy admixtures decrease magnetic properties and lifting capacity.
- Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Health Danger
Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Handling guide
Be careful. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can react.
Bone fractures
Risk of injury: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Use thick gloves.
Magnets are brittle
Watch out for shards. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.
Protect data
Powerful magnetic fields can destroy records on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Precision electronics
Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Maintain a separation from your mobile, tablet, and GPS.
Nickel coating and allergies
Some people have a sensitization to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact can result in dermatitis. It is best to use safety gloves.
Choking Hazard
Neodymium magnets are not intended for children. Swallowing several magnets may result in them connecting inside the digestive tract, which constitutes a critical condition and requires immediate surgery.
Thermal limits
Do not overheat. NdFeB magnets are sensitive to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Flammability
Machining of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
