Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They do not lose magnetism, even over nearly 10 years – the drop in strength is only ~1% (based on measurements),
- They maintain their magnetic properties even under external field action,
- By applying a lustrous layer of silver, the element has an nice look,
- Magnetic induction on the top side of the magnet remains extremely intense,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of individual creating and optimizing to defined conditions,
- Huge importance in high-tech industry – they are used in computer drives, motor assemblies, precision medical tools, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions
Limitations
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- NdFeB magnets lose force 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 - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complicated forms in magnets, we recommend using cover - magnetic mechanism.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small components of these products can complicate diagnosis medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- using a base made of mild steel, serving as a magnetic yoke
- possessing a thickness of min. 10 mm to avoid saturation
- with an ground touching surface
- with total lack of distance (without coatings)
- during detachment in a direction perpendicular to the plane
- at room temperature
Determinants of lifting force in real conditions
- Distance (betwixt the magnet and the metal), as even a tiny clearance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Load vector – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be wasted into the air.
- Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate lowers the lifting capacity.
Safety rules for work with NdFeB magnets
Dust is flammable
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Danger to pacemakers
Patients with a ICD should maintain an safe separation from magnets. The magnetism can disrupt the functioning of the implant.
Operating temperature
Keep cool. NdFeB magnets are sensitive to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Magnet fragility
Beware of splinters. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Cards and drives
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
GPS Danger
Note: neodymium magnets generate a field that confuses sensitive sensors. Keep a safe distance from your phone, tablet, and navigation systems.
Bodily injuries
Big blocks can break fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
Avoid contact if allergic
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, cease handling magnets and use protective gear.
Keep away from children
Product intended for adults. Tiny parts can be swallowed, causing severe trauma. Keep out of reach of children and animals.
Immense force
Be careful. Neodymium magnets attract from a distance and connect with massive power, often faster than you can move away.
