Advantages and disadvantages of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- They are extremely resistant to demagnetization induced by external magnetic fields,
- Thanks to the shiny finish, the layer of Ni-Cu-Ni, gold, or silver gives an elegant appearance,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to the possibility of precise shaping and customization to custom solutions, magnetic components can be produced in a variety of shapes and sizes, which amplifies use scope,
- Versatile presence in modern technologies – they are used in HDD drives, electric drive systems, medical devices, and technologically advanced constructions.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Disadvantages
- At strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (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
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of making threads in the magnet and complicated forms - preferred is casing - mounting mechanism.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small components of these magnets can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Highest magnetic holding force – what contributes to it?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- with a cross-section no less than 10 mm
- characterized by even structure
- with direct contact (no coatings)
- under axial force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Plate thickness – too thin plate does not close the flux, causing part of the flux to be escaped into the air.
- Metal type – different alloys reacts the same. High carbon content weaken the attraction effect.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Operating temperature – neodymium magnets have a sensitivity to temperature. 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 the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet and the plate lowers the lifting capacity.
H&S for magnets
Dust is flammable
Drilling and cutting of NdFeB material carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Beware of splinters
Protect your eyes. Magnets can fracture upon violent connection, launching shards into the air. We recommend safety glasses.
GPS and phone interference
Remember: neodymium magnets produce a field that disrupts precision electronics. Keep a separation from your phone, tablet, and navigation systems.
Medical implants
Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Protect data
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, timepieces).
Permanent damage
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.
Allergy Warning
A percentage of the population suffer from a sensitization to nickel, which is the common plating for NdFeB magnets. Frequent touching might lead to a rash. We strongly advise wear protective gloves.
Danger to the youngest
Always store magnets away from children. Ingestion danger is significant, and the effects of magnets connecting inside the body are fatal.
Hand protection
Protect your hands. Two large magnets will join instantly with a force of massive weight, destroying anything in their path. Be careful!
Handling guide
Handle with care. Rare earth magnets attract from a distance and snap with massive power, often quicker than you can react.
