Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They possess excellent resistance to magnetic field loss when exposed to external fields,
- In other words, due to the smooth finish of silver, the element is aesthetically pleasing,
- Neodymium magnets deliver maximum magnetic induction on a small area, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- In view of the possibility of accurate forming and adaptation to custom requirements, magnetic components can be produced in a wide range of shapes and sizes, which amplifies use scope,
- Significant place in high-tech industry – they serve a role in data components, electromotive mechanisms, medical equipment, also modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which allows their use in compact constructions
Disadvantages
- To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and 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
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of creating nuts in the magnet and complicated forms - recommended is a housing - magnet mounting.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical when they are in 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
Holding force characteristics
Highest magnetic holding force – what contributes to it?
- with the contact of a yoke made of special test steel, ensuring maximum field concentration
- possessing a thickness of min. 10 mm to avoid saturation
- characterized by smoothness
- without any insulating layer between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Gap (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin steel does not accept the full field, causing part of the power to be escaped to the other side.
- Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
- Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was measured by applying a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Safe handling of neodymium magnets
Magnets are brittle
Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Powerful field
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Threat to electronics
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can permanently damage these devices and erase data from cards.
Swallowing risk
Always keep magnets out of reach of children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are fatal.
Combustion hazard
Fire warning: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
Physical harm
Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!
Thermal limits
Regular neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Magnetic interference
A powerful magnetic field disrupts the operation of compasses in phones and GPS navigation. Maintain magnets near a smartphone to avoid breaking the sensors.
Avoid contact if allergic
Certain individuals experience a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching may cause skin redness. It is best to use safety gloves.
ICD Warning
Patients with a heart stimulator have to maintain an absolute distance from magnets. The magnetism can stop the functioning of the implant.
