Strengths and weaknesses of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
- They possess excellent resistance to magnetism drop as a result of external magnetic sources,
- In other words, due to the metallic surface of gold, the element gains visual value,
- Magnetic induction on the surface of the magnet turns out to be exceptional,
- 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...
- Thanks to freedom in forming and the ability to adapt to complex applications,
- Versatile presence in electronics industry – they are commonly used in HDD drives, drive modules, medical equipment, as well as technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in miniature devices
Cons
- At strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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 extremely resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of making nuts in the magnet and complex shapes - preferred is cover - magnetic holder.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these devices can complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is economically unviable,
Lifting parameters
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the application of a yoke made of special test steel, ensuring maximum field concentration
- whose transverse dimension equals approx. 10 mm
- with a surface cleaned and smooth
- without the slightest clearance between the magnet and steel
- under vertical force direction (90-degree angle)
- at ambient temperature room level
What influences lifting capacity in practice
- Clearance – the presence of foreign body (paint, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Load vector – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Hardened steels may attract less.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
Warnings
No play value
NdFeB magnets are not toys. Eating several magnets can lead to them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
Maximum temperature
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and strength.
Respect the power
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Be predictive.
Allergy Warning
Some people experience a contact allergy to nickel, which is the common plating for neodymium magnets. Extended handling might lead to a rash. We recommend wear safety gloves.
Pacemakers
Health Alert: Strong magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Bone fractures
Watch your fingers. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
Protective goggles
Despite the nickel coating, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Data carriers
Very strong magnetic fields can erase data on payment cards, hard drives, and storage devices. Maintain a gap of at least 10 cm.
Flammability
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
GPS Danger
GPS units and mobile phones are highly susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
