Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- Their power remains stable, and after approximately ten years it drops only by ~1% (theoretically),
- They maintain their magnetic properties even under strong external field,
- Thanks to the shimmering finish, the coating of Ni-Cu-Ni, gold-plated, or silver gives an visually attractive appearance,
- They show high magnetic induction at the operating surface, making them more effective,
- 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...
- In view of the potential of free molding and adaptation to specialized requirements, magnetic components can be manufactured in a broad palette of shapes and sizes, which increases their versatility,
- Wide application in high-tech industry – they serve a role in magnetic memories, electric drive systems, advanced medical instruments, as well as technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in realizing nuts and complex forms in magnets, we recommend using cover - magnetic mount.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets can complicate diagnosis medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- with the application of a yoke made of low-carbon steel, guaranteeing full magnetic saturation
- with a thickness no less than 10 mm
- characterized by smoothness
- with direct contact (no impurities)
- during detachment in a direction perpendicular to the plane
- at conditions approx. 20°C
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Metal type – not every steel attracts identically. Alloy additives weaken the attraction effect.
- Smoothness – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
- Thermal environment – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under a perpendicular pulling force, whereas under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate lowers the holding force.
Safety rules for work with neodymium magnets
Medical interference
Warning for patients: Strong magnetic fields affect electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Demagnetization risk
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Threat to navigation
A strong magnetic field negatively affects the operation of magnetometers in phones and GPS navigation. Maintain magnets near a smartphone to avoid breaking the sensors.
Allergic reactions
A percentage of the population have a hypersensitivity to Ni, which is the standard coating for neodymium magnets. Prolonged contact might lead to dermatitis. We suggest use safety gloves.
Crushing force
Protect your hands. Two large magnets will snap together immediately with a force of massive weight, crushing anything in their path. Be careful!
Handling guide
Handle magnets with awareness. Their huge power can shock even professionals. Plan your moves and respect their force.
Protective goggles
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Dust is flammable
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Cards and drives
Avoid bringing magnets close to a purse, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Do not give to children
Neodymium magnets are not suitable for play. Eating multiple magnets can lead to them attracting across intestines, which poses a critical condition and requires urgent medical intervention.
