Strengths as well as weaknesses of rare earth magnets.
Advantages
- Their strength is maintained, and after approximately ten years it decreases only by ~1% (according to research),
- They are extremely resistant to demagnetization induced by external disturbances,
- Thanks to the shimmering finish, the plating of Ni-Cu-Ni, gold-plated, or silver-plated gives an elegant appearance,
- Neodymium magnets create maximum magnetic induction on a their surface, which allows for strong attraction,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- In view of the option of flexible shaping and customization to custom needs, NdFeB magnets can be manufactured in a broad palette of geometric configurations, which increases their versatility,
- Wide application in innovative solutions – they are used in magnetic memories, electric drive systems, medical equipment, as well as industrial machines.
- 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 using a steel holder. Such protection not only shields the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited ability of making nuts in the magnet and complex forms - preferred is cover - mounting mechanism.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small elements of these magnets are able to complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- with an ideally smooth touching surface
- without the slightest insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Steel thickness – insufficiently thick sheet does not accept the full field, causing part of the flux to be wasted into the air.
- Chemical composition of the base – mild steel gives the best results. Alloy steels reduce magnetic permeability and lifting capacity.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Threat to electronics
Device Safety: Strong magnets can ruin data carriers and sensitive devices (pacemakers, medical aids, timepieces).
Eye protection
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Keep away from electronics
An intense magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Keep magnets close to a device to avoid damaging the sensors.
Danger to pacemakers
For implant holders: Strong magnetic fields disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Warning for allergy sufferers
Allergy Notice: The nickel-copper-nickel coating contains nickel. If an allergic reaction happens, immediately stop working with magnets and use protective gear.
Fire risk
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Respect the power
Exercise caution. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can move away.
Maximum temperature
Do not overheat. Neodymium magnets are sensitive to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Danger to the youngest
Product intended for adults. Tiny parts pose a choking risk, causing severe trauma. Keep out of reach of children and animals.
Serious injuries
Danger of trauma: The pulling power is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
