Strengths as well as weaknesses of neodymium magnets.
Benefits
- Their strength is durable, and after around ten years it drops only by ~1% (theoretically),
- They do not lose their magnetic properties even under external field action,
- In other words, due to the shiny finish of silver, the element gains visual value,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which ensures high operational effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in forming and the capacity to customize to complex applications,
- Wide application in innovative solutions – they are used in computer drives, drive modules, advanced medical instruments, as well as modern systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in realizing nuts and complicated forms in magnets, we recommend using cover - magnetic holder.
- Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. It is also worth noting that tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what affects it?
- with the use of a sheet made of special test steel, guaranteeing full magnetic saturation
- with a thickness minimum 10 mm
- with a plane free of scratches
- without the slightest clearance between the magnet and steel
- under perpendicular force vector (90-degree angle)
- in stable room temperature
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the metal), since even a very small distance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
- Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Metal type – not every steel attracts identically. Alloy additives weaken the interaction with the magnet.
- Surface structure – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Safe distance
Avoid bringing magnets close to a wallet, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.
Metal Allergy
Certain individuals experience a contact allergy to nickel, which is the standard coating for neodymium magnets. Extended handling may cause a rash. We suggest use protective gloves.
Fragile material
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. Eye protection is mandatory.
Crushing force
Large magnets can break fingers in a fraction of a second. Under no circumstances put your hand between two attracting surfaces.
Choking Hazard
Always keep magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are tragic.
Pacemakers
Medical warning: Strong magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Precision electronics
Note: rare earth magnets generate a field that confuses sensitive sensors. Maintain a safe distance from your mobile, device, and GPS.
Dust explosion hazard
Fire warning: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.
Maximum temperature
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and strength.
Caution required
Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
