Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
- They maintain their magnetic properties even under close interference source,
- A magnet with a smooth nickel surface is more attractive,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Thanks to resistance to high temperature, they can operate (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of precise forming and modifying to concrete needs,
- Huge importance in innovative solutions – they find application in mass storage devices, drive modules, advanced medical instruments, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in miniature devices
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing threads and complex shapes in magnets, we recommend using a housing - magnetic mount.
- Health risk related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these devices can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what contributes to it?
- on a plate made of structural steel, optimally conducting the magnetic field
- with a cross-section of at least 10 mm
- with a plane perfectly flat
- with total lack of distance (no impurities)
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Gap (betwixt the magnet and the plate), since even a tiny clearance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (typically approx. 20-30% of nominal force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys attracts identically. Alloy additives worsen the attraction effect.
- Surface condition – ground elements guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a slight gap between the magnet’s surface and the plate decreases the load capacity.
H&S for magnets
Keep away from computers
Equipment safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Implant safety
Health Alert: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Keep away from children
Absolutely store magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are tragic.
Material brittleness
Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Serious injuries
Big blocks can crush fingers instantly. Do not place your hand betwixt two attracting surfaces.
Flammability
Machining of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Heat warning
Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its properties and pulling force.
Conscious usage
Use magnets with awareness. Their huge power can surprise even professionals. Be vigilant and respect their power.
Allergic reactions
Certain individuals suffer from a contact allergy to Ni, which is the standard coating for neodymium magnets. Extended handling might lead to a rash. We strongly advise wear protective gloves.
Phone sensors
An intense magnetic field interferes with the operation of magnetometers in phones and navigation systems. Keep magnets near a smartphone to avoid damaging the sensors.
