Other proposals
Pros as well as cons of Nd2Fe14B magnets.
Advantages
- Their strength is maintained, and after approximately ten years it drops only by ~1% (theoretically),
- They retain their magnetic properties even under close interference source,
- A magnet with a shiny gold surface is more attractive,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to versatility in designing and the ability to modify to individual projects,
- Significant place in advanced technology sectors – they are utilized in data components, brushless drives, medical devices, and other advanced devices.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- At strong impacts they can crack, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complicated forms in magnets, we propose using casing - magnetic holder.
- Potential hazard to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these devices are able to disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets is economically unviable,
Lifting parameters
Maximum lifting force for a neodymium magnet – what it depends on?
- with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
- whose thickness equals approx. 10 mm
- with a surface cleaned and smooth
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction perpendicular to the plane
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Material composition – not every steel reacts the same. High carbon content worsen the interaction with the magnet.
- Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Operating temperature – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Warnings
Caution required
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Keep away from computers
Do not bring magnets near a wallet, laptop, or screen. The magnetic field can permanently damage these devices and erase data from cards.
Pacemakers
Warning for patients: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Mechanical processing
Fire hazard: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
Skin irritation risks
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, immediately stop working with magnets and use protective gear.
Magnet fragility
Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Bodily injuries
Danger of trauma: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Protective gloves are recommended.
Thermal limits
Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Adults only
Adult use only. Small elements can be swallowed, causing serious injuries. Store away from kids and pets.
GPS and phone interference
GPS units and mobile phones are highly sensitive to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
