Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They do not lose strength, even after around ten years – the drop in power is only ~1% (theoretically),
- Magnets very well defend themselves against demagnetization caused by external fields,
- In other words, due to the glossy finish of gold, the element becomes visually attractive,
- Magnetic induction on the surface of the magnet remains strong,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Due to the option of free shaping and customization to specialized solutions, magnetic components can be manufactured in a variety of shapes and sizes, which increases their versatility,
- Wide application in advanced technology sectors – they are commonly used in HDD drives, electric drive systems, advanced medical instruments, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in small systems
Disadvantages
- 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 start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Due to limitations in producing nuts and complicated forms in magnets, we propose using a housing - magnetic mount.
- Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small components of these magnets can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum holding power of the magnet – what affects it?
- with the contact of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- with a cross-section of at least 10 mm
- with a plane perfectly flat
- without any air gap between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- at room temperature
Lifting capacity in practice – influencing factors
- Gap between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Plate material – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Medical implants
For implant holders: Powerful magnets affect medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Sensitization to coating
Some people have a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Frequent touching might lead to a rash. We suggest wear protective gloves.
Precision electronics
An intense magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Do not bring magnets near a smartphone to avoid breaking the sensors.
Protective goggles
Beware of splinters. Magnets can fracture upon violent connection, launching shards into the air. Wear goggles.
Powerful field
Handle magnets with awareness. Their huge power can shock even professionals. Stay alert and do not underestimate their force.
Data carriers
Do not bring magnets close to a purse, laptop, or screen. The magnetic field can destroy these devices and erase data from cards.
Keep away from children
These products are not intended for children. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which poses a critical condition and necessitates immediate surgery.
Heat sensitivity
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and pulling force.
Pinching danger
Danger of trauma: The attraction force is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Fire risk
Fire hazard: Neodymium dust is explosive. Avoid machining magnets without safety gear as this risks ignition.
