Pros as well as cons of neodymium magnets.
Benefits
- Their strength remains stable, and after around 10 years it decreases only by ~1% (theoretically),
- Neodymium magnets remain exceptionally resistant to magnetic field loss caused by magnetic disturbances,
- A magnet with a metallic gold surface has better aesthetics,
- Magnetic induction on the working part of the magnet remains impressive,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures approaching 230°C and above...
- In view of the option of accurate shaping and adaptation to specialized projects, NdFeB magnets can be created in a wide range of shapes and sizes, which amplifies use scope,
- Significant place in modern industrial fields – they are commonly used in computer drives, electric drive systems, advanced medical instruments, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems
Cons
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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 when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of producing threads in the magnet and complex shapes - recommended is cover - magnet mounting.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Furthermore, tiny parts of these products can be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- with the use of a yoke made of special test steel, ensuring maximum field concentration
- with a thickness minimum 10 mm
- characterized by smoothness
- without any air gap between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at room temperature
Practical aspects of lifting capacity – factors
- Distance (betwixt the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick steel does not close the flux, causing part of the flux to be wasted to the other side.
- Material composition – not every steel reacts the same. High carbon content worsen the attraction effect.
- Base smoothness – the more even the surface, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet and the plate decreases the load capacity.
Safety rules for work with neodymium magnets
Handling guide
Handle with care. Neodymium magnets act from a long distance and snap with massive power, often faster than you can move away.
Threat to electronics
Very strong magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Flammability
Powder generated during cutting of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Medical interference
Patients with a ICD must maintain an safe separation from magnets. The magnetism can interfere with the functioning of the life-saving device.
Risk of cracking
Neodymium magnets are sintered ceramics, which means they are very brittle. Impact of two magnets leads to them breaking into shards.
Allergy Warning
Some people suffer from a sensitization to Ni, which is the standard coating for neodymium magnets. Prolonged contact can result in dermatitis. We suggest use safety gloves.
Thermal limits
Keep cool. Neodymium magnets are sensitive to heat. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
GPS and phone interference
Remember: neodymium magnets generate a field that disrupts precision electronics. Maintain a safe distance from your phone, tablet, and navigation systems.
Bodily injuries
Large magnets can break fingers in a fraction of a second. Under no circumstances place your hand between two attracting surfaces.
Do not give to children
These products are not suitable for play. Swallowing a few magnets can lead to them pinching intestinal walls, which poses a severe health hazard and requires immediate surgery.
