Pros and cons of rare earth magnets.
Pros
- They retain magnetic properties for nearly 10 years – the loss is just ~1% (according to analyses),
- They maintain their magnetic properties even under close interference source,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnets are characterized by huge magnetic induction on the active area,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Due to the ability of flexible forming and customization to unique needs, magnetic components can be manufactured in a broad palette of shapes and sizes, which makes them more universal,
- Wide application in high-tech industry – they are commonly used in data components, electric drive systems, precision medical tools, as well as modern systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only shields 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
- 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 a housing - magnetic mount.
- Possible danger to health – tiny shards of magnets pose a threat, 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 magnets are able to complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum magnetic pulling force – what it depends on?
- on a base made of structural steel, perfectly concentrating the magnetic flux
- whose transverse dimension equals approx. 10 mm
- with a plane perfectly flat
- without any insulating layer between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- at temperature room level
Practical lifting capacity: influencing factors
- Distance (between the magnet and the plate), because even a very small clearance (e.g. 0.5 mm) results in a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Metal type – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
Safety rules for work with NdFeB magnets
Do not drill into magnets
Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Physical harm
Risk of injury: The attraction force is so great that it can cause hematomas, pinching, and broken bones. Protective gloves are recommended.
Power loss in heat
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.
Do not underestimate power
Handle magnets consciously. Their powerful strength can surprise even experienced users. Stay alert and do not underestimate their force.
Skin irritation risks
A percentage of the population experience a sensitization to Ni, which is the standard coating for neodymium magnets. Prolonged contact may cause skin redness. We suggest use safety gloves.
Protect data
Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Stay away of min. 10 cm.
GPS Danger
Remember: neodymium magnets produce a field that interferes with precision electronics. Maintain a separation from your mobile, device, and navigation systems.
No play value
Adult use only. Tiny parts pose a choking risk, causing severe trauma. Keep away from children and animals.
Fragile material
Despite the nickel coating, the material is brittle and cannot withstand shocks. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
Warning for heart patients
Patients with a pacemaker have to keep an absolute distance from magnets. The magnetism can stop the functioning of the life-saving device.
