Advantages and disadvantages of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
- They maintain their magnetic properties even under close interference source,
- By covering with a reflective coating of gold, the element has an nice look,
- Magnets exhibit maximum magnetic induction on the outer layer,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Possibility of exact creating as well as adjusting to specific applications,
- Significant place in modern industrial fields – they are used in mass storage devices, brushless drives, advanced medical instruments, as well as technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Cons
- To avoid cracks under impact, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- NdFeB magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
- Limited ability of making nuts in the magnet and complicated forms - preferred is a housing - magnet mounting.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
- whose transverse dimension equals approx. 10 mm
- with an polished touching surface
- without any air gap between the magnet and steel
- under vertical force direction (90-degree angle)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Distance (between the magnet and the plate), because even a tiny clearance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
- Angle of force application – maximum parameter is reached only during pulling at a 90° angle. The force required to slide of the magnet along the plate is standardly many times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick plate does not accept the full field, causing part of the power to be wasted to the other side.
- Metal type – not every steel reacts the same. High carbon content weaken the attraction effect.
- Plate texture – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Thermal factor – high temperature reduces magnetic field. Too high temperature can permanently demagnetize the magnet.
Lifting capacity testing was carried out on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with neodymium magnets
Threat to electronics
Intense magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of min. 10 cm.
Swallowing risk
These products are not intended for children. Eating a few magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.
Allergy Warning
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, avoid direct skin contact and choose versions in plastic housing.
Warning for heart patients
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Handling guide
Be careful. Rare earth magnets attract from a long distance and connect with massive power, often quicker than you can react.
Bodily injuries
Pinching hazard: The pulling power is so great that it can cause blood blisters, crushing, and even bone fractures. Use thick gloves.
Power loss in heat
Avoid heat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Fire warning
Combustion risk: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.
Impact on smartphones
A strong magnetic field negatively affects the operation of compasses in smartphones and navigation systems. Keep magnets near a device to prevent damaging the sensors.
Magnet fragility
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
