Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They have unchanged lifting capacity, and over nearly 10 years their performance decreases symbolically – ~1% (in testing),
- They maintain their magnetic properties even under external field action,
- In other words, due to the reflective surface of nickel, the element gains a professional look,
- Magnets have excellent magnetic induction on the outer side,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in shaping and the ability to customize to complex applications,
- Huge importance in electronics industry – they are used in mass storage devices, drive modules, medical equipment, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in small systems
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- Neodymium magnets lose their strength 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 stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- Limited ability of making nuts in the magnet and complicated forms - preferred is casing - magnet mounting.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- using a base made of mild steel, serving as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- with a plane cleaned and smooth
- without the slightest air gap between the magnet and steel
- under axial force vector (90-degree angle)
- at ambient temperature room level
Practical aspects of lifting capacity – factors
- Distance – existence of any layer (paint, dirt, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick plate does not close the flux, causing part of the power to be lost into the air.
- Chemical composition of the base – mild steel attracts best. Higher carbon content decrease magnetic properties and lifting capacity.
- Plate texture – ground elements ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under parallel forces the load capacity is reduced by as much as 5 times. Moreover, even a small distance between the magnet and the plate reduces the lifting capacity.
Safe handling of neodymium magnets
Medical interference
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Heat sensitivity
Watch the temperature. Exposing the magnet to high heat will permanently weaken its magnetic structure and strength.
Warning for allergy sufferers
Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, immediately stop handling magnets and use protective gear.
GPS Danger
Remember: neodymium magnets produce a field that disrupts sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
Finger safety
Risk of injury: The pulling power is so great that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Protect data
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetic field can permanently damage these devices and erase data from cards.
Beware of splinters
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Collision of two magnets will cause them shattering into small pieces.
Safe operation
Before starting, check safety instructions. Sudden snapping can break the magnet or injure your hand. Be predictive.
Danger to the youngest
NdFeB magnets are not toys. Accidental ingestion of a few magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.
Dust explosion hazard
Dust generated during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
