Pros as well as cons of Nd2Fe14B magnets.
Benefits
- They do not lose power, even after nearly ten years – the drop in lifting capacity is only ~1% (theoretically),
- They do not lose their magnetic properties even under close interference source,
- In other words, due to the reflective finish of nickel, the element gains a professional look,
- Magnets possess huge magnetic induction on the surface,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- In view of the possibility of free molding and adaptation to unique projects, NdFeB magnets can be created in a broad palette of shapes and sizes, which increases their versatility,
- Huge importance in future technologies – they are utilized in mass storage devices, brushless drives, medical devices, also multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Cons
- 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 reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex shapes in magnets, we propose using a housing - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which gains importance in the context of child health protection. Furthermore, small components of these products are able to complicate diagnosis medical when they are in the body.
- Due to expensive raw materials, their price is higher than average,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a plate made of structural steel, effectively closing the magnetic flux
- with a cross-section of at least 10 mm
- with a plane cleaned and smooth
- without the slightest air gap between the magnet and steel
- during pulling in a direction vertical to the plane
- at standard ambient temperature
What influences lifting capacity in practice
- Distance (betwixt the magnet and the plate), since even a very small clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and holding force.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate reduces the holding force.
H&S for magnets
Nickel coating and allergies
Nickel alert: The nickel-copper-nickel coating consists of nickel. If redness appears, immediately stop handling magnets and wear gloves.
Protective goggles
Despite metallic appearance, the material is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Bone fractures
Big blocks can break fingers instantly. Do not put your hand between two attracting surfaces.
Medical interference
Individuals with a ICD must maintain an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Heat sensitivity
Do not overheat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).
No play value
Neodymium magnets are not toys. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which poses a critical condition and necessitates urgent medical intervention.
Handling guide
Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often faster than you can react.
Magnetic media
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Fire risk
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
GPS and phone interference
A strong magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Keep magnets close to a smartphone to avoid damaging the sensors.
