Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- Neodymium magnets are characterized by extremely resistant to magnetic field loss caused by magnetic disturbances,
- Thanks to the shiny finish, the plating of Ni-Cu-Ni, gold, or silver-plated gives an professional appearance,
- Neodymium magnets ensure maximum magnetic induction on a contact point, which increases force concentration,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the ability of free shaping and customization to custom needs, neodymium magnets can be created in a wide range of forms and dimensions, which amplifies use scope,
- Huge importance in modern technologies – they are utilized in hard drives, electric drive systems, diagnostic systems, as well as 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
Disadvantages
- They are fragile upon too strong 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
- When exposed to high temperature, neodymium magnets suffer a drop in power. 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 during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We recommend cover - magnetic holder, due to difficulties in creating nuts inside the magnet and complex forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, tiny parts of these products can be problematic in diagnostics medical when they are in the body.
- Due to neodymium price, their price is higher than average,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the application of a yoke made of low-carbon steel, ensuring full magnetic saturation
- whose thickness is min. 10 mm
- with an ground touching surface
- without the slightest clearance between the magnet and steel
- for force applied at a right angle (in the magnet axis)
- at ambient temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance – the presence of any layer (paint, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material type – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. In addition, even a small distance between the magnet and the plate reduces the lifting capacity.
Safety rules for work with neodymium magnets
Flammability
Dust created during cutting of magnets is combustible. Do not drill into magnets unless you are an expert.
Demagnetization risk
Do not overheat. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Life threat
For implant holders: Powerful magnets disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Allergy Warning
Certain individuals have a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact may cause an allergic reaction. It is best to use protective gloves.
Do not underestimate power
Exercise caution. Neodymium magnets attract from a distance and snap with huge force, often faster than you can react.
Threat to navigation
Navigation devices and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can permanently damage the sensors in your phone.
Data carriers
Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.
Eye protection
Despite the nickel coating, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Hand protection
Large magnets can smash fingers instantly. Under no circumstances place your hand betwixt two strong magnets.
Adults only
Absolutely keep magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are tragic.
