Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They have constant strength, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets are characterized by exceptionally resistant to magnetic field loss caused by magnetic disturbances,
- Thanks to the shiny finish, the coating of nickel, gold-plated, or silver gives an elegant appearance,
- The surface of neodymium magnets generates a strong magnetic field – this is a key feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures approaching 230°C and above...
- Thanks to modularity in shaping and the ability to modify to unusual requirements,
- Versatile presence in modern technologies – they are used in magnetic memories, electromotive mechanisms, medical equipment, also industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Cons
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. 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 during using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing nuts and complex forms in magnets, we propose using a housing - magnetic mechanism.
- Health risk related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, tiny parts of these products can complicate diagnosis medical after entering the body.
- With mass production the cost of neodymium magnets is economically unviable,
Pull force analysis
Magnetic strength at its maximum – what it depends on?
- with the contact of a sheet made of low-carbon steel, ensuring full magnetic saturation
- possessing a thickness of min. 10 mm to ensure full flux closure
- with an ground touching surface
- under conditions of no distance (surface-to-surface)
- under vertical application of breakaway force (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick steel does not accept the full field, causing part of the flux to be wasted to the other side.
- Material type – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Smoothness – ideal contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with neodymium magnets
Safe distance
Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, medical aids, mechanical watches).
Machining danger
Dust produced during machining of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Conscious usage
Handle with care. Rare earth magnets act from a distance and connect with massive power, often quicker than you can react.
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, cease working with magnets and wear gloves.
Maximum temperature
Do not overheat. Neodymium magnets are susceptible to heat. If you need resistance above 80°C, inquire about HT versions (H, SH, UH).
Bodily injuries
Risk of injury: The attraction force is so great that it can result in blood blisters, crushing, and broken bones. Protective gloves are recommended.
ICD Warning
Warning for patients: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
Magnetic interference
Navigation devices and smartphones are highly sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
This is not a toy
Adult use only. Tiny parts pose a choking risk, leading to serious injuries. Store out of reach of kids and pets.
Eye protection
NdFeB magnets are sintered ceramics, which means they are very brittle. Collision of two magnets will cause them breaking into shards.
