Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They have stable power, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- They are noted for resistance to demagnetization induced by external field influence,
- A magnet with a metallic nickel surface is more attractive,
- Magnetic induction on the working layer of the magnet turns out to be very high,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to freedom in shaping and the capacity to customize to individual projects,
- Wide application in advanced technology sectors – they are used in magnetic memories, motor assemblies, medical equipment, as well as technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in steel cases. 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 advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in realizing nuts and complex forms in magnets, we propose using a housing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Additionally, small elements of these devices can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Highest magnetic holding force – what affects it?
- on a plate made of structural steel, effectively closing the magnetic flux
- with a cross-section no less than 10 mm
- with a plane cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- during detachment in a direction vertical to the mounting surface
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Gap (betwixt the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Higher carbon content decrease magnetic properties and lifting capacity.
- Plate texture – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Thermal environment – 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 pulling force, in contrast under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate decreases the lifting capacity.
Do not overheat magnets
Control the heat. Exposing the magnet to high heat will permanently weaken its properties and pulling force.
Phone sensors
A strong magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Do not bring magnets close to a smartphone to avoid damaging the sensors.
ICD Warning
Individuals with a heart stimulator should keep an safe separation from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Threat to electronics
Avoid bringing magnets near a wallet, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Handling rules
Be careful. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can move away.
Crushing risk
Pinching hazard: The attraction force is so great that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Mechanical processing
Powder created during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Shattering risk
Beware of splinters. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Sensitization to coating
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If redness happens, cease working with magnets and wear gloves.
Do not give to children
Only for adults. Small elements can be swallowed, leading to serious injuries. Keep out of reach of children and animals.
