Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- They retain their magnetic properties even under external field action,
- In other words, due to the metallic layer of gold, the element is aesthetically pleasing,
- Magnets exhibit maximum magnetic induction on the active area,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to modularity in constructing and the ability to customize to individual projects,
- Universal use in advanced technology sectors – they are utilized in mass storage devices, brushless drives, precision medical tools, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in miniature devices
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 very resistant to heat
- When exposed to humidity, magnets start to rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- Limited ability of making threads in the magnet and complex forms - preferred is cover - magnet mounting.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these products can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Magnetic strength at its maximum – what it depends on?
- using a base made of mild steel, functioning as a magnetic yoke
- possessing a massiveness of at least 10 mm to avoid saturation
- with an ideally smooth touching surface
- under conditions of gap-free contact (surface-to-surface)
- under vertical application of breakaway force (90-degree angle)
- in temp. approx. 20°C
Key elements affecting lifting force
- Distance (between the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
- Base massiveness – insufficiently thick steel does not accept the full field, causing part of the power to be lost into the air.
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the load capacity is reduced by as much as 5 times. In addition, even a small distance between the magnet and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Physical harm
Protect your hands. Two powerful magnets will join immediately with a force of massive weight, destroying everything in their path. Be careful!
Maximum temperature
Watch the temperature. Heating the magnet to high heat will destroy its magnetic structure and strength.
Adults only
These products are not suitable for play. Swallowing several magnets may result in them pinching intestinal walls, which poses a severe health hazard and requires urgent medical intervention.
Handling rules
Handle with care. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can move away.
Fragile material
Protect your eyes. Magnets can fracture upon violent connection, launching shards into the air. We recommend safety glasses.
Do not drill into magnets
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Health Danger
Patients with a heart stimulator have to maintain an absolute distance from magnets. The magnetic field can interfere with the functioning of the implant.
Metal Allergy
Some people suffer from a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching can result in an allergic reaction. We suggest use safety gloves.
Keep away from electronics
Note: rare earth magnets produce a field that confuses sensitive sensors. Keep a separation from your phone, device, and GPS.
Safe distance
Powerful magnetic fields can erase data on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.
