Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- Magnets very well defend themselves against loss of magnetization caused by external fields,
- Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the option of flexible forming and adaptation to specialized projects, magnetic components can be manufactured in a wide range of geometric configurations, which increases their versatility,
- Versatile presence in high-tech industry – they are commonly used in mass storage devices, electromotive mechanisms, advanced medical instruments, as well as modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Disadvantages
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing nuts in the magnet and complex shapes - preferred is casing - mounting mechanism.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. Additionally, small components of these devices are able to complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- on a plate made of structural steel, perfectly concentrating the magnetic flux
- with a thickness of at least 10 mm
- with an polished touching surface
- with total lack of distance (without coatings)
- during pulling in a direction perpendicular to the plane
- at standard ambient temperature
What influences lifting capacity in practice
- Distance – the presence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Plate material – mild steel attracts best. Higher carbon content decrease magnetic permeability and lifting capacity.
- Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Magnetic interference
Remember: neodymium magnets produce a field that disrupts sensitive sensors. Maintain a safe distance from your phone, tablet, and GPS.
Fire risk
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Do not overheat magnets
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. This process is irreversible.
Bone fractures
Big blocks can break fingers in a fraction of a second. Never place your hand between two attracting surfaces.
Electronic devices
Very strong magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.
Sensitization to coating
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
Danger to pacemakers
People with a pacemaker have to keep an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.
Protective goggles
Watch out for shards. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Conscious usage
Exercise caution. Rare earth magnets attract from a distance and connect with massive power, often quicker than you can move away.
Swallowing risk
NdFeB magnets are not intended for children. Eating a few magnets may result in them attracting across intestines, which poses a severe health hazard and requires urgent medical intervention.
