Pros and cons of Nd2Fe14B magnets.
Benefits
- Their strength remains stable, and after around ten years it drops only by ~1% (according to research),
- They possess excellent resistance to magnetism drop when exposed to external fields,
- Thanks to the smooth finish, the plating of nickel, gold, or silver gives an modern appearance,
- Magnets exhibit very high magnetic induction on the outer side,
- 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 flexibility in shaping and the capacity to customize to specific needs,
- Significant place in future technologies – they are used in magnetic memories, motor assemblies, diagnostic systems, as well as multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At very strong impacts they can break, therefore we advise placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complicated shapes in magnets, we propose using a housing - magnetic mechanism.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- With large orders the cost of neodymium magnets is a challenge,
Holding force characteristics
Maximum holding power of the magnet – what contributes to it?
- on a base made of mild steel, optimally conducting the magnetic field
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a plane perfectly flat
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Air gap (betwixt the magnet and the plate), since even a microscopic clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Direction of force – maximum parameter is available only during perpendicular pulling. The resistance to sliding of the magnet along the plate is usually several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
- Surface finish – full contact is possible only on polished steel. Rough texture create air cushions, weakening the magnet.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was determined with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under shearing force the lifting capacity is smaller. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Precautions when working with NdFeB magnets
Fire risk
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Pacemakers
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Data carriers
Equipment safety: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, timepieces).
Handling rules
Use magnets consciously. Their huge power can surprise even professionals. Stay alert and do not underestimate their power.
Metal Allergy
Medical facts indicate that nickel (standard magnet coating) is a strong allergen. If your skin reacts to metals, avoid touching magnets with bare hands and choose encased magnets.
Crushing risk
Big blocks can smash fingers instantly. Under no circumstances place your hand between two attracting surfaces.
Permanent damage
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and pulling force.
This is not a toy
NdFeB magnets are not suitable for play. Swallowing several magnets can lead to them pinching intestinal walls, which constitutes a severe health hazard and necessitates immediate surgery.
Beware of splinters
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them breaking into small pieces.
Keep away from electronics
An intense magnetic field negatively affects the functioning of compasses in smartphones and navigation systems. Do not bring magnets near a smartphone to prevent breaking the sensors.
