Pros as well as cons of Nd2Fe14B magnets.
Advantages
- They retain attractive force for around 10 years – the loss is just ~1% (based on simulations),
- They retain their magnetic properties even under close interference source,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets are distinguished by impressive magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to modularity in constructing and the capacity to modify to individual projects,
- Versatile presence in modern technologies – they are utilized in computer drives, brushless drives, medical devices, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in small systems
Cons
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- We warn that neodymium magnets can reduce their power 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 while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend casing - magnetic mechanism, due to difficulties in realizing nuts inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which is particularly important in the context of child safety. Additionally, small components of these devices can disrupt the diagnostic process medical when they are in the body.
- With budget limitations the cost of neodymium magnets can be a barrier,
Pull force analysis
Highest magnetic holding force – what it depends on?
- using a plate made of mild steel, acting as a ideal flux conductor
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a surface cleaned and smooth
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Air gap (between the magnet and the metal), because even a very small distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to varnish, rust or debris).
- Load vector – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of converting into lifting capacity.
- Steel type – mild steel attracts best. Higher carbon content lower magnetic properties and lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Life threat
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.
Respect the power
Handle magnets with awareness. Their powerful strength can surprise even experienced users. Be vigilant and respect their power.
Heat sensitivity
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Threat to electronics
Data protection: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, medical aids, timepieces).
Dust is flammable
Drilling and cutting of NdFeB material poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Protective goggles
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Magnetic interference
Note: rare earth magnets produce a field that confuses precision electronics. Keep a separation from your mobile, device, and navigation systems.
Sensitization to coating
Some people experience a contact allergy to Ni, which is the standard coating for neodymium magnets. Extended handling might lead to an allergic reaction. We suggest use protective gloves.
Do not give to children
Product intended for adults. Tiny parts can be swallowed, causing serious injuries. Keep out of reach of children and animals.
Crushing force
Pinching hazard: The pulling power is so immense that it can cause blood blisters, pinching, and even bone fractures. Use thick gloves.
