Strengths as well as weaknesses of Nd2Fe14B magnets.
Benefits
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- They show high resistance to demagnetization induced by external magnetic fields,
- By applying a shiny layer of silver, the element has an proper look,
- Magnets exhibit huge magnetic induction on the working surface,
- 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...
- In view of the potential of flexible shaping and customization to unique needs, magnetic components can be manufactured in a wide range of shapes and sizes, which increases their versatility,
- Significant place in innovative solutions – they are used in magnetic memories, brushless drives, medical equipment, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in miniature devices
Weaknesses
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 very resistant to heat
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- Limited ability of producing nuts in the magnet and complicated shapes - recommended is a housing - magnetic holder.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, tiny parts of these products can disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- using a sheet made of mild steel, acting as a magnetic yoke
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with a surface perfectly flat
- under conditions of no distance (metal-to-metal)
- during detachment in a direction perpendicular to the plane
- in neutral thermal conditions
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Direction of force – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – mild steel attracts best. Alloy steels decrease magnetic properties and holding force.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Temperature – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the holding force.
Safe handling of neodymium magnets
Sensitization to coating
Studies show that the nickel plating (the usual finish) is a strong allergen. For allergy sufferers, prevent touching magnets with bare hands or opt for coated magnets.
Power loss in heat
Watch the temperature. Heating the magnet to high heat will destroy its properties and strength.
Threat to navigation
GPS units and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Danger to pacemakers
For implant holders: Powerful magnets affect electronics. Keep minimum 30 cm distance or ask another person to work with the magnets.
Conscious usage
Use magnets consciously. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their power.
Magnetic media
Equipment safety: Strong magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, timepieces).
No play value
Neodymium magnets are not intended for children. Eating a few magnets may result in them attracting across intestines, which constitutes a direct threat to life and necessitates urgent medical intervention.
Eye protection
NdFeB magnets are sintered ceramics, which means they are very brittle. Clashing of two magnets will cause them cracking into shards.
Machining danger
Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this risks ignition.
Hand protection
Protect your hands. Two powerful magnets will join instantly with a force of massive weight, crushing anything in their path. Be careful!
