Pros and cons of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- They are noted for resistance to demagnetization induced by external field influence,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the working layer of the magnet is strong,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Due to the ability of flexible shaping and adaptation to unique requirements, neodymium magnets can be created in a broad palette of forms and dimensions, which amplifies use scope,
- Versatile presence in modern technologies – they are used in data components, electric motors, diagnostic systems, also complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power 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
- 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, when using outdoors
- We suggest a housing - magnetic mount, due to difficulties in producing threads inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Additionally, tiny parts of these products are able to complicate diagnosis medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- using a plate made of low-carbon steel, functioning as a circuit closing element
- whose thickness equals approx. 10 mm
- with an polished contact surface
- with zero gap (no paint)
- for force acting at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Key elements affecting lifting force
- Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When slipping, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Plate material – mild steel attracts best. Alloy steels lower magnetic permeability and lifting capacity.
- Smoothness – ideal contact is obtained only on smooth steel. Rough texture create air cushions, weakening the magnet.
- Thermal environment – heating the magnet causes a temporary drop of induction. Check the thermal limit for a given model.
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Impact on smartphones
Be aware: rare earth magnets produce a field that disrupts sensitive sensors. Maintain a separation from your mobile, device, and navigation systems.
Material brittleness
Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Dust explosion hazard
Fire warning: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Hand protection
Pinching hazard: The attraction force is so great that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.
Medical interference
Warning for patients: Strong magnetic fields affect medical devices. Maintain at least 30 cm distance or request help to handle the magnets.
Handling rules
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Sensitization to coating
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, immediately stop handling magnets and wear gloves.
Maximum temperature
Monitor thermal conditions. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
Safe distance
Intense magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Product not for children
Always store magnets away from children. Choking hazard is high, and the effects of magnets clamping inside the body are fatal.
