Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They do not lose power, even after nearly 10 years – the decrease in lifting capacity is only ~1% (according to tests),
- Neodymium magnets are distinguished by remarkably resistant to magnetic field loss caused by external interference,
- A magnet with a smooth silver surface is more attractive,
- Magnetic induction on the working layer of the magnet turns out to be impressive,
- 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...
- Thanks to freedom in shaping and the capacity to modify to client solutions,
- Versatile presence in future technologies – they are used in magnetic memories, motor assemblies, medical equipment, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in compact constructions
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mount, due to difficulties in producing threads inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Magnetic strength at its maximum – what it depends on?
- with the contact of a sheet made of special test steel, guaranteeing full magnetic saturation
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a surface free of scratches
- under conditions of gap-free contact (surface-to-surface)
- under perpendicular force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Gap (between the magnet and the plate), as even a very small distance (e.g. 0.5 mm) leads to a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Chemical composition of the base – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Rough surfaces weaken the grip.
- Thermal factor – high temperature reduces pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was determined with the use of a polished steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Warnings
GPS and phone interference
A strong magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Do not bring magnets near a smartphone to prevent breaking the sensors.
Do not drill into magnets
Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.
Immense force
Handle magnets with awareness. Their immense force can shock even experienced users. Plan your moves and respect their power.
Adults only
Neodymium magnets are not intended for children. Eating multiple magnets may result in them connecting inside the digestive tract, which constitutes a severe health hazard and requires urgent medical intervention.
Data carriers
Powerful magnetic fields can erase data on payment cards, HDDs, and storage devices. Keep a distance of min. 10 cm.
Danger to pacemakers
Patients with a pacemaker have to maintain an large gap from magnets. The magnetic field can interfere with the operation of the life-saving device.
Crushing force
Risk of injury: The attraction force is so great that it can result in hematomas, crushing, and broken bones. Protective gloves are recommended.
Power loss in heat
Do not overheat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Eye protection
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Avoid contact if allergic
Studies show that nickel (the usual finish) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands and choose versions in plastic housing.
