Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- Magnets perfectly defend themselves against loss of magnetization caused by ambient magnetic noise,
- Thanks to the metallic finish, the plating of nickel, gold, or silver gives an clean appearance,
- Magnetic induction on the surface of the magnet is 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 versatility in shaping and the ability to modify to unusual requirements,
- Significant place in future technologies – they serve a role in HDD drives, electromotive mechanisms, advanced medical instruments, and other advanced devices.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets lose their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of making threads in the magnet and complex forms - preferred is casing - magnet mounting.
- Possible danger resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
- Due to neodymium price, their price is higher than average,
Pull force analysis
Maximum magnetic pulling force – what contributes to it?
- using a sheet made of low-carbon steel, acting as a ideal flux conductor
- with a thickness no less than 10 mm
- with a surface perfectly flat
- without any clearance between the magnet and steel
- during pulling in a direction vertical to the plane
- at room temperature
Lifting capacity in practice – influencing factors
- Clearance – existence of foreign body (rust, tape, gap) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures decrease magnetic permeability and lifting capacity.
- Surface finish – ideal contact is possible only on polished steel. Rough texture reduce the real contact area, reducing force.
- Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was conducted 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. In addition, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Warnings
Magnetic media
Very strong magnetic fields can erase data on payment cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Handling guide
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Phone sensors
A powerful magnetic field interferes with the operation of compasses in phones and GPS navigation. Keep magnets near a device to avoid damaging the sensors.
Serious injuries
Large magnets can break fingers in a fraction of a second. Never place your hand betwixt two strong magnets.
Demagnetization risk
Regular neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. The loss of strength is permanent.
Swallowing risk
Only for adults. Tiny parts can be swallowed, leading to severe trauma. Keep away from children and animals.
Implant safety
Life threat: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Combustion hazard
Dust generated during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Metal Allergy
Warning for allergy sufferers: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease handling magnets and use protective gear.
Magnet fragility
Despite metallic appearance, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
