Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They have constant strength, and over more than 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They possess excellent resistance to magnetic field loss as a result of opposing magnetic fields,
- By applying a decorative coating of nickel, the element gains an aesthetic look,
- Magnets are distinguished by impressive magnetic induction on the active area,
- 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...
- Possibility of detailed shaping as well as adapting to defined needs,
- Significant place in modern industrial fields – they serve a role in computer drives, brushless drives, medical equipment, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Cons
- At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 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 protecting against moisture
- We recommend cover - magnetic mount, due to difficulties in producing threads inside the magnet and complex forms.
- Possible danger related to microscopic parts of magnets are risky, in case of ingestion, which becomes key in the context of child safety. It is also worth noting that small elements of these magnets are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Maximum lifting force for a neodymium magnet – what affects it?
- with the use of a sheet made of low-carbon steel, ensuring maximum field concentration
- with a cross-section no less than 10 mm
- characterized by even structure
- without the slightest insulating layer between the magnet and steel
- under axial force vector (90-degree angle)
- in neutral thermal conditions
Practical aspects of lifting capacity – factors
- Space between surfaces – every millimeter of separation (caused e.g. by varnish or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Angle of force application – highest force is obtained only during perpendicular pulling. The force required to slide of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface finish – ideal contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Warnings
Handling rules
Use magnets with awareness. Their powerful strength can shock even experienced users. Be vigilant and respect their power.
Electronic devices
Powerful magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Protective goggles
Watch out for shards. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.
Medical interference
Individuals with a ICD have to maintain an large gap from magnets. The magnetism can interfere with the functioning of the life-saving device.
GPS Danger
A strong magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a device to avoid damaging the sensors.
Do not drill into magnets
Dust created during machining of magnets is combustible. Do not drill into magnets unless you are an expert.
Power loss in heat
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Keep away from children
Always keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are very dangerous.
Hand protection
Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Avoid contact if allergic
Studies show that nickel (the usual finish) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for coated magnets.
