Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (according to literature),
- Magnets perfectly defend themselves against demagnetization caused by external fields,
- By using a shiny coating of gold, the element gains an modern look,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which allows for strong attraction,
- 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 precise forming as well as adjusting to atypical applications,
- Universal use in modern industrial fields – they are commonly used in data components, electric motors, advanced medical instruments, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in compact constructions
Weaknesses
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- We recommend casing - magnetic mount, due to difficulties in producing nuts inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, tiny parts of these products can disrupt the diagnostic process medical in case of swallowing.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- using a sheet made of mild steel, functioning as a circuit closing element
- possessing a massiveness of minimum 10 mm to avoid saturation
- with an ideally smooth contact surface
- under conditions of no distance (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Lifting capacity in practice – influencing factors
- Clearance – the presence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Metal type – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Uneven metal reduce efficiency.
- Temperature – temperature increase results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Compass and GPS
A powerful magnetic field disrupts the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a device to avoid breaking the sensors.
Eye protection
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets leads to them cracking into shards.
Conscious usage
Be careful. Neodymium magnets act from a long distance and snap with huge force, often quicker than you can react.
Electronic hazard
Intense magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Maintain a gap of min. 10 cm.
Heat warning
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. This process is irreversible.
Choking Hazard
Absolutely keep magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are life-threatening.
Life threat
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Flammability
Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Warning for allergy sufferers
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands or select coated magnets.
Crushing force
Large magnets can crush fingers instantly. Under no circumstances put your hand between two strong magnets.
