Strengths and weaknesses of neodymium magnets.
Advantages
- Their magnetic field remains stable, and after around ten years it drops only by ~1% (theoretically),
- They maintain their magnetic properties even under external field action,
- A magnet with a shiny nickel surface has better aesthetics,
- They show high magnetic induction at the operating surface, which increases their power,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to the potential of flexible forming and adaptation to custom requirements, neodymium magnets can be manufactured in a wide range of forms and dimensions, which expands the range of possible applications,
- Fundamental importance in modern technologies – they are utilized in hard drives, drive modules, medical devices, and complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited ability of producing threads in the magnet and complex shapes - recommended is cover - magnet mounting.
- Potential hazard related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Best holding force of the magnet in ideal parameters – what contributes to it?
- with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- characterized by smoothness
- with direct contact (no coatings)
- under vertical force direction (90-degree angle)
- in neutral thermal conditions
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet holds much less (often approx. 20-30% of maximum force).
- Plate thickness – insufficiently thick steel does not accept the full field, causing part of the power to be lost to the other side.
- Plate material – mild steel attracts best. Alloy admixtures reduce magnetic permeability and holding force.
- Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under a perpendicular pulling force, however under shearing force the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Material brittleness
Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Mechanical processing
Drilling and cutting of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Warning for allergy sufferers
Allergy Notice: The Ni-Cu-Ni coating contains nickel. If skin irritation happens, cease working with magnets and use protective gear.
Handling guide
Be careful. Neodymium magnets act from a distance and snap with huge force, often faster than you can react.
Do not overheat magnets
Regular neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Adults only
Neodymium magnets are not intended for children. Swallowing multiple magnets may result in them pinching intestinal walls, which poses a critical condition and requires urgent medical intervention.
Bone fractures
Pinching hazard: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Electronic hazard
Powerful magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Phone sensors
Note: neodymium magnets generate a field that confuses sensitive sensors. Keep a safe distance from your mobile, tablet, and navigation systems.
ICD Warning
Patients with a pacemaker must maintain an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.
