Other offers
Strengths as well as weaknesses of rare earth magnets.
Advantages
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- Magnets effectively defend themselves against demagnetization caused by external fields,
- In other words, due to the metallic surface of nickel, the element gains a professional look,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which increases force concentration,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling functioning at temperatures approaching 230°C and above...
- Possibility of precise shaping as well as adapting to atypical needs,
- Significant place in advanced technology sectors – they find application in magnetic memories, brushless drives, medical equipment, and other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose power 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
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mount, due to difficulties in producing nuts inside the magnet and complex shapes.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that small components of these magnets are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- using a base made of high-permeability steel, functioning as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- with an ground touching surface
- without any clearance between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Practical lifting capacity: influencing factors
- Distance (betwixt the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or debris).
- Direction of force – maximum parameter is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of generating force.
- Metal type – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface condition – ground elements guarantee perfect abutment, which increases force. Uneven metal reduce efficiency.
- Thermal factor – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as 5 times. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Do not give to children
Product intended for adults. Tiny parts pose a choking risk, leading to serious injuries. Store out of reach of kids and pets.
Precision electronics
Remember: rare earth magnets produce a field that confuses sensitive sensors. Maintain a safe distance from your phone, device, and navigation systems.
Powerful field
Handle magnets with awareness. Their huge power can surprise even experienced users. Be vigilant and respect their power.
Machining danger
Dust generated during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Warning for heart patients
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Crushing risk
Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!
Keep away from computers
Data protection: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Nickel coating and allergies
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, cease handling magnets and use protective gear.
Thermal limits
Keep cool. NdFeB magnets are sensitive to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Magnets are brittle
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into hazardous fragments.
