Advantages and disadvantages of Nd2Fe14B magnets.
Pros
- They do not lose magnetism, even after approximately ten years – the drop in power is only ~1% (based on measurements),
- They do not lose their magnetic properties even under close interference source,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- They feature high magnetic induction at the operating surface, making them more effective,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to versatility in shaping and the ability to modify to individual projects,
- Versatile presence in high-tech industry – they are utilized in hard drives, motor assemblies, medical equipment, also modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their force 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in realizing threads and complex forms in magnets, we propose using cover - magnetic mount.
- Potential hazard related to microscopic parts of magnets are risky, if swallowed, which becomes key in the context of child safety. Furthermore, small elements of these products are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- using a sheet made of high-permeability steel, serving as a ideal flux conductor
- whose transverse dimension is min. 10 mm
- characterized by even structure
- with total lack of distance (without impurities)
- for force applied at a right angle (in the magnet axis)
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (paint, dirt, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Plate thickness – too thin steel does not accept the full field, causing part of the flux to be lost into the air.
- Material composition – not every steel attracts identically. Alloy additives worsen the interaction with the magnet.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
Warnings
Permanent damage
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its magnetic structure and strength.
Electronic devices
Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.
Adults only
Absolutely store magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are life-threatening.
Material brittleness
NdFeB magnets are ceramic materials, which means they are very brittle. Impact of two magnets will cause them breaking into small pieces.
Do not underestimate power
Handle magnets consciously. Their immense force can shock even professionals. Stay alert and do not underestimate their power.
ICD Warning
For implant holders: Strong magnetic fields affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Nickel coating and allergies
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, immediately stop working with magnets and use protective gear.
Impact on smartphones
Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Dust is flammable
Powder produced during machining of magnets is flammable. Do not drill into magnets without proper cooling and knowledge.
Finger safety
Big blocks can crush fingers instantly. Never put your hand betwixt two strong magnets.
