Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They do not lose strength, even over around 10 years – the decrease in lifting capacity is only ~1% (theoretically),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- By applying a decorative coating of gold, the element has an proper look,
- Neodymium magnets create maximum magnetic induction on a small area, which increases force concentration,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of exact shaping and adapting to precise needs,
- Fundamental importance in innovative solutions – they are used in data components, drive modules, diagnostic systems, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which allows their use in compact constructions
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making threads in the magnet and complex shapes - preferred is cover - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which becomes key in the context of child health protection. It is also worth noting that small components of these products are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- with the contact of a yoke made of low-carbon steel, ensuring maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with a plane cleaned and smooth
- without any insulating layer between the magnet and steel
- under vertical force vector (90-degree angle)
- at room temperature
Practical lifting capacity: influencing factors
- Gap between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Angle of force application – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin steel does not close the flux, causing part of the power to be lost to the other side.
- Material composition – not every steel attracts identically. High carbon content weaken the interaction with the magnet.
- Smoothness – full contact is obtained only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate lowers the holding force.
Safe handling of neodymium magnets
Pacemakers
For implant holders: Powerful magnets disrupt electronics. Keep at least 30 cm distance or ask another person to work with the magnets.
Heat warning
Do not overheat. Neodymium magnets are sensitive to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
Safe distance
Intense magnetic fields can erase data on payment cards, hard drives, and storage devices. Stay away of min. 10 cm.
Flammability
Dust generated during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, immediately stop working with magnets and wear gloves.
Physical harm
Big blocks can crush fingers instantly. Do not put your hand betwixt two strong magnets.
Threat to navigation
A powerful magnetic field disrupts the functioning of compasses in phones and GPS navigation. Do not bring magnets close to a smartphone to avoid breaking the sensors.
Immense force
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Magnet fragility
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Swallowing risk
Adult use only. Small elements can be swallowed, leading to severe trauma. Keep away from children and animals.
