Pros and cons of neodymium magnets.
Benefits
- They retain full power for around ten years – the drop is just ~1% (based on simulations),
- They do not lose their magnetic properties even under close interference source,
- In other words, due to the aesthetic surface of nickel, the element gains visual value,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- 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 possibility of precise shaping and adaptation to unique requirements, NdFeB magnets can be modeled in a wide range of shapes and sizes, which amplifies use scope,
- Wide application in modern technologies – they are utilized in HDD drives, electric drive systems, diagnostic systems, as well as modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Weaknesses
- At very strong impacts they can crack, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complex shapes.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum holding power of the magnet – what affects it?
- with the contact of a yoke made of special test steel, ensuring maximum field concentration
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a plane free of scratches
- with zero gap (without impurities)
- during pulling in a direction vertical to the plane
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Distance (betwixt the magnet and the metal), because even a very small distance (e.g. 0.5 mm) can cause a decrease in force by up to 50% (this also applies to paint, rust or dirt).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
- Steel type – low-carbon steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal environment – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked 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 75%. Moreover, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.
Precautions when working with NdFeB magnets
Impact on smartphones
An intense magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to prevent breaking the sensors.
Product not for children
Always keep magnets away from children. Risk of swallowing is high, and the effects of magnets connecting inside the body are tragic.
Bone fractures
Danger of trauma: The pulling power is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Medical implants
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Dust explosion hazard
Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Nickel allergy
Medical facts indicate that nickel (the usual finish) is a strong allergen. If you have an allergy, avoid direct skin contact and choose versions in plastic housing.
Electronic devices
Do not bring magnets near a purse, laptop, or TV. The magnetism can destroy these devices and erase data from cards.
Protective goggles
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Thermal limits
Do not overheat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Handling guide
Handle magnets consciously. Their powerful strength can surprise even experienced users. Be vigilant and do not underestimate their power.
