Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They do not lose power, even over approximately 10 years – the drop in lifting capacity is only ~1% (according to tests),
- Neodymium magnets are characterized by remarkably resistant to demagnetization caused by external magnetic fields,
- Thanks to the shimmering finish, the coating of nickel, gold-plated, or silver-plated gives an aesthetic appearance,
- Magnets are distinguished by exceptionally strong magnetic induction on the outer layer,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- In view of the option of free forming and adaptation to custom needs, neodymium magnets can be created in a variety of shapes and sizes, which amplifies use scope,
- Fundamental importance in future technologies – they find application in magnetic memories, motor assemblies, medical equipment, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in compact constructions
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only protects them against impacts but also raises their durability
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend a housing - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child health protection. It is also worth noting that small components of these products are able to be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- using a sheet made of high-permeability steel, functioning as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- with an ground contact surface
- under conditions of ideal adhesion (metal-to-metal)
- during pulling in a direction perpendicular to the mounting surface
- in neutral thermal conditions
What influences lifting capacity in practice
- Air gap (betwixt the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, corrosion or dirt).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Rough surfaces reduce efficiency.
- Thermal environment – heating the magnet causes a temporary drop of force. Check the thermal limit for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Allergic reactions
Studies show that nickel (standard magnet coating) is a potent allergen. If you have an allergy, prevent touching magnets with bare hands and opt for encased magnets.
Danger to the youngest
Adult use only. Tiny parts pose a choking risk, causing intestinal necrosis. Store away from kids and pets.
Electronic hazard
Avoid bringing magnets near a wallet, computer, or screen. The magnetic field can destroy these devices and erase data from cards.
Health Danger
For implant holders: Strong magnetic fields affect medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.
Hand protection
Big blocks can break fingers in a fraction of a second. Never place your hand betwixt two attracting surfaces.
Respect the power
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Eye protection
NdFeB magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets leads to them breaking into shards.
Impact on smartphones
Navigation devices and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Do not overheat magnets
Regular neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Do not drill into magnets
Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.
