Advantages and disadvantages of Nd2Fe14B magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (based on calculations),
- They are resistant to demagnetization induced by external magnetic fields,
- Thanks to the metallic finish, the surface of Ni-Cu-Ni, gold, or silver gives an professional appearance,
- The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
- 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 modularity in constructing and the ability to adapt to unusual requirements,
- Significant place in modern technologies – they find application in hard drives, drive modules, advanced medical instruments, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in compact constructions
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using cover - magnetic mount.
- Potential hazard resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- using a plate made of high-permeability steel, serving as a ideal flux conductor
- whose thickness is min. 10 mm
- with a plane free of scratches
- with direct contact (without impurities)
- under axial application of breakaway force (90-degree angle)
- at temperature room level
Determinants of lifting force in real conditions
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the pulling force, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Thermal factor – high temperature reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as 75%. In addition, even a small distance between the magnet and the plate decreases the load capacity.
Precautions when working with NdFeB magnets
Heat sensitivity
Do not overheat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Fire warning
Machining of NdFeB material carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Crushing risk
Large magnets can crush fingers in a fraction of a second. Do not place your hand between two strong magnets.
Adults only
Always store magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are very dangerous.
Data carriers
Data protection: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, timepieces).
Respect the power
Before starting, check safety instructions. Uncontrolled attraction can break the magnet or injure your hand. Think ahead.
Protective goggles
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. Wear goggles.
GPS Danger
An intense magnetic field disrupts the operation of magnetometers in phones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.
Nickel coating and allergies
Medical facts indicate that nickel (the usual finish) is a potent allergen. For allergy sufferers, refrain from direct skin contact and opt for encased magnets.
Warning for heart patients
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
