Pros and cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- They have excellent resistance to magnetism drop due to opposing magnetic fields,
- Thanks to the metallic finish, the coating of nickel, gold-plated, or silver gives an aesthetic appearance,
- Magnets are distinguished by huge magnetic induction on the outer layer,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Considering the option of flexible shaping and adaptation to custom solutions, NdFeB magnets can be created in a variety of geometric configurations, which makes them more universal,
- Key role in high-tech industry – they are commonly used in data components, electromotive mechanisms, medical devices, and other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in miniature devices
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited ability of producing nuts in the magnet and complex shapes - recommended is cover - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. It is also worth noting that small components of these devices are able to be problematic in diagnostics medical after entering the body.
- Due to neodymium price, their price is higher than average,
Lifting parameters
Detachment force of the magnet in optimal conditions – what contributes to it?
- with the application of a sheet made of low-carbon steel, ensuring maximum field concentration
- with a cross-section of at least 10 mm
- with a surface free of scratches
- under conditions of gap-free contact (metal-to-metal)
- under perpendicular application of breakaway force (90-degree angle)
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be wasted into the air.
- Chemical composition of the base – mild steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
- Smoothness – ideal contact is possible only on polished steel. Rough texture create air cushions, reducing force.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under shearing force the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet and the plate reduces the holding force.
Precautions when working with neodymium magnets
Pinching danger
Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying anything in their path. Be careful!
Handling rules
Be careful. Neodymium magnets act from a distance and connect with huge force, often quicker than you can react.
GPS and phone interference
GPS units and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.
Shattering risk
NdFeB magnets are ceramic materials, meaning they are very brittle. Collision of two magnets will cause them breaking into shards.
Medical implants
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Data carriers
Device Safety: Neodymium magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, mechanical watches).
Allergic reactions
Studies show that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, prevent touching magnets with bare hands and select versions in plastic housing.
Adults only
Neodymium magnets are not intended for children. Accidental ingestion of several magnets can lead to them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
Fire warning
Dust produced during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Heat sensitivity
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
