Advantages and disadvantages of rare earth magnets.
Strengths
- They have constant strength, and over nearly ten years their attraction force decreases symbolically – ~1% (according to theory),
- They show high resistance to demagnetization induced by external field influence,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- The surface of neodymium magnets generates a powerful magnetic field – this is one of their assets,
- 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...
- Thanks to the option of flexible shaping and adaptation to specialized needs, neodymium magnets can be produced in a broad palette of shapes and sizes, which increases their versatility,
- Versatile presence in modern industrial fields – they serve a role in hard drives, motor assemblies, advanced medical instruments, as well as complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce 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 immune to moisture, when using outdoors
- Limited ability of making threads in the magnet and complicated forms - recommended is casing - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these devices can be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Lifting parameters
Maximum lifting force for a neodymium magnet – what contributes to it?
- with the use of a yoke made of special test steel, guaranteeing full magnetic saturation
- possessing a thickness of at least 10 mm to ensure full flux closure
- with a plane free of scratches
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction perpendicular to the plane
- at temperature room level
Magnet lifting force in use – key factors
- Distance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Steel grade – the best choice is pure iron steel. Hardened steels may have worse magnetic properties.
- Surface quality – the more even the surface, the larger the contact zone and stronger the hold. Unevenness creates an air distance.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Compass and GPS
Navigation devices and mobile phones are highly sensitive to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.
Nickel allergy
Medical facts indicate that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, refrain from direct skin contact or select encased magnets.
Handling guide
Use magnets with awareness. Their immense force can shock even professionals. Plan your moves and respect their force.
Machining danger
Dust created during grinding of magnets is flammable. Avoid drilling into magnets without proper cooling and knowledge.
Thermal limits
Control the heat. Exposing the magnet to high heat will ruin its magnetic structure and strength.
Implant safety
Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Adults only
Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Store away from children and animals.
Physical harm
Big blocks can break fingers instantly. Do not put your hand betwixt two strong magnets.
Cards and drives
Very strong magnetic fields can erase data on payment cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
Magnet fragility
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
