Strengths and weaknesses of neodymium magnets.
Advantages
- Their power is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
- They are extremely resistant to demagnetization induced by presence of other magnetic fields,
- In other words, due to the aesthetic finish of nickel, the element gains a professional look,
- Magnets have exceptionally strong magnetic induction on the active area,
- 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...
- Considering the ability of free forming and adaptation to specialized projects, NdFeB magnets can be created in a variety of geometric configurations, which amplifies use scope,
- Fundamental importance in modern technologies – they are commonly used in HDD drives, brushless drives, advanced medical instruments, as well as multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in creating nuts and complicated forms in magnets, we propose using casing - magnetic mechanism.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that small components of these products can be problematic in diagnostics medical when they are in the body.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Maximum lifting capacity of the magnet – what affects it?
- using a base made of low-carbon steel, serving as a circuit closing element
- with a cross-section minimum 10 mm
- characterized by even structure
- under conditions of gap-free contact (surface-to-surface)
- during detachment in a direction vertical to the plane
- in temp. approx. 20°C
Practical lifting capacity: influencing factors
- Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Load vector – maximum parameter is reached only during perpendicular pulling. The shear force of the magnet along the surface is typically several times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Plate material – low-carbon steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with NdFeB magnets
Thermal limits
Avoid heat. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Fire warning
Dust generated during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Compass and GPS
Remember: rare earth magnets produce a field that interferes with sensitive sensors. Keep a safe distance from your mobile, device, and GPS.
Risk of cracking
Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
Danger to pacemakers
Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Do not give to children
Strictly keep magnets out of reach of children. Ingestion danger is high, and the effects of magnets connecting inside the body are very dangerous.
Avoid contact if allergic
Certain individuals have a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Extended handling might lead to dermatitis. It is best to use safety gloves.
Hand protection
Protect your hands. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Be careful!
Electronic hazard
Data protection: Strong magnets can ruin data carriers and sensitive devices (heart implants, medical aids, timepieces).
Safe operation
Be careful. Rare earth magnets act from a long distance and snap with massive power, often faster than you can react.
