Pros and cons of Nd2Fe14B magnets.
Pros
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (in laboratory conditions),
- Magnets effectively resist against demagnetization caused by foreign field sources,
- In other words, due to the glossy surface of nickel, the element is aesthetically pleasing,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- In view of the possibility of precise molding and customization to custom requirements, magnetic components can be produced in a broad palette of shapes and sizes, which amplifies use scope,
- Versatile presence in advanced technology sectors – they find application in data components, drive modules, diagnostic systems, and other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- At strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex shapes.
- Health risk to health – tiny shards of magnets pose a threat, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small components of these products are able to complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price exceeds standard values,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a plate made of mild steel, optimally conducting the magnetic field
- with a cross-section minimum 10 mm
- with a surface cleaned and smooth
- with direct contact (without impurities)
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Practical aspects of lifting capacity – factors
- Air gap (between the magnet and the plate), since 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 paint, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Material composition – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
- Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Avoid contact if allergic
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If skin irritation happens, cease working with magnets and wear gloves.
Power loss in heat
Regular neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. The loss of strength is permanent.
No play value
Only for adults. Small elements pose a choking risk, causing serious injuries. Store away from kids and pets.
Protect data
Equipment safety: Neodymium magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).
Crushing risk
Big blocks can smash fingers instantly. Never place your hand between two strong magnets.
Pacemakers
Patients with a heart stimulator have to maintain an large gap from magnets. The magnetic field can disrupt the functioning of the implant.
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Dust explosion hazard
Drilling and cutting of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
GPS Danger
GPS units and smartphones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Fragile material
Protect your eyes. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
