Strengths and weaknesses of Nd2Fe14B magnets.
Pros
- Their power remains stable, and after approximately 10 years it decreases only by ~1% (according to research),
- Magnets very well defend themselves against demagnetization caused by external fields,
- Thanks to the elegant finish, the coating of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures reaching 230°C and above...
- Thanks to flexibility in shaping and the ability to customize to specific needs,
- Huge importance in modern technologies – they serve a role in mass storage devices, electric drive systems, advanced medical instruments, also technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- Brittleness is one of their disadvantages. Upon strong 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 force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Due to limitations in realizing threads and complex shapes in magnets, we propose using casing - magnetic mount.
- Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these devices can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- using a base made of high-permeability steel, acting as a circuit closing element
- possessing a thickness of min. 10 mm to avoid saturation
- with an ideally smooth touching surface
- without any air gap between the magnet and steel
- during pulling in a direction perpendicular to the mounting surface
- at conditions approx. 20°C
Magnet lifting force in use – key factors
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Plate material – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, weakening the magnet.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the holding force is lower. Additionally, even a small distance between the magnet and the plate lowers the lifting capacity.
Safety rules for work with NdFeB magnets
Mechanical processing
Dust generated during cutting of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Maximum temperature
Standard neodymium magnets (grade N) lose power when the temperature exceeds 80°C. Damage is permanent.
Sensitization to coating
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If you have an allergy, avoid touching magnets with bare hands or choose coated magnets.
Conscious usage
Be careful. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can move away.
Crushing risk
Watch your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Medical implants
Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Precision electronics
Navigation devices and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Safe distance
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetic field can destroy these devices and erase data from cards.
Material brittleness
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets will cause them cracking into shards.
Adults only
Only for adults. Tiny parts can be swallowed, leading to intestinal necrosis. Keep out of reach of children and animals.
