Strengths as well as weaknesses of rare earth magnets.
Pros
- They do not lose strength, even during around 10 years – the drop in lifting capacity is only ~1% (theoretically),
- Neodymium magnets are distinguished by remarkably resistant to demagnetization caused by external magnetic fields,
- In other words, due to the shiny layer of nickel, the element gains a professional look,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which increases force concentration,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Considering the possibility of free shaping and adaptation to individualized requirements, magnetic components can be produced in a broad palette of geometric configurations, which expands the range of possible applications,
- Huge importance in advanced technology sectors – they are utilized in data components, electric drive systems, advanced medical instruments, as well as modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (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 extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We suggest a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small components of these products can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- using a sheet made of low-carbon steel, acting as a magnetic yoke
- whose thickness reaches at least 10 mm
- with a plane cleaned and smooth
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction perpendicular to the mounting surface
- in stable room temperature
Practical lifting capacity: influencing factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Cast iron may generate lower lifting capacity.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Unevenness acts like micro-gaps.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under perpendicular forces, whereas under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Safe handling of neodymium magnets
This is not a toy
Always store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are very dangerous.
Heat warning
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Do not underestimate power
Before starting, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Pinching danger
Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing everything in their path. Exercise extreme caution!
Sensitization to coating
Certain individuals suffer from a contact allergy to nickel, which is the common plating for neodymium magnets. Prolonged contact might lead to a rash. We suggest use safety gloves.
Implant safety
Life threat: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Dust is flammable
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Keep away from electronics
Navigation devices and mobile phones are extremely susceptible to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.
Protect data
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Beware of splinters
Beware of splinters. Magnets can explode upon uncontrolled impact, launching shards into the air. Wear goggles.
