Pros as well as cons of neodymium magnets.
Benefits
- They virtually do not lose strength, because even after ten years the performance loss is only ~1% (according to literature),
- They have excellent resistance to magnetic field loss when exposed to external fields,
- A magnet with a shiny nickel surface is more attractive,
- Neodymium magnets create maximum magnetic induction on a their surface, which increases force concentration,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Thanks to modularity in forming and the capacity to adapt to unusual requirements,
- Significant place in modern industrial fields – they are used in mass storage devices, drive modules, advanced medical instruments, and multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only shields the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complicated forms in magnets, we recommend using cover - magnetic mechanism.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- using a plate made of mild steel, serving as a ideal flux conductor
- whose transverse dimension is min. 10 mm
- with an polished touching surface
- with total lack of distance (without impurities)
- under axial force vector (90-degree angle)
- at room temperature
Determinants of practical lifting force of a magnet
- Distance (betwixt the magnet and the metal), since even a microscopic distance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (often approx. 20-30% of nominal force).
- Plate thickness – too thin plate causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Metal type – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, however under shearing force the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Warnings
Allergic reactions
Some people experience a contact allergy to nickel, which is the common plating for NdFeB magnets. Extended handling can result in a rash. We recommend wear protective gloves.
Phone sensors
A powerful magnetic field disrupts the operation of compasses in smartphones and navigation systems. Keep magnets close to a device to prevent damaging the sensors.
Bodily injuries
Danger of trauma: The pulling power is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Eye protection
Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Eye protection is mandatory.
Safe distance
Device Safety: Strong magnets can ruin payment cards and sensitive devices (heart implants, hearing aids, timepieces).
Fire warning
Drilling and cutting of NdFeB material carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Caution required
Use magnets with awareness. Their immense force can shock even experienced users. Be vigilant and do not underestimate their force.
ICD Warning
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Do not approach if you have electronic implants.
Maximum temperature
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.
Do not give to children
Always store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets connecting inside the body are very dangerous.
