Advantages and disadvantages of rare earth magnets.
Pros
- Their magnetic field remains stable, and after approximately ten years it decreases only by ~1% (theoretically),
- Magnets perfectly resist against loss of magnetization caused by foreign field sources,
- Thanks to the metallic finish, the surface of nickel, gold, or silver gives an visually attractive appearance,
- Neodymium magnets achieve maximum magnetic induction on a small surface, which ensures high operational effectiveness,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to freedom in designing and the ability to customize to unusual requirements,
- Universal use in innovative solutions – they serve a role in data components, electric drive systems, medical equipment, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which allows their use in miniature devices
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing threads in the magnet and complicated forms - preferred is cover - mounting mechanism.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Additionally, small components of these magnets can disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Holding force characteristics
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a plate made of mild steel, effectively closing the magnetic flux
- with a cross-section of at least 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (metal-to-metal)
- under vertical application of breakaway force (90-degree angle)
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Distance – existence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
- Plate thickness – too thin sheet does not accept the full field, causing part of the power to be escaped to the other side.
- Steel type – low-carbon steel gives the best results. Alloy steels lower magnetic properties and lifting capacity.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature – heating the magnet results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the load capacity is reduced by as much as 5 times. In addition, even a slight gap between the magnet and the plate reduces the holding force.
Safe handling of neodymium magnets
Keep away from computers
Device Safety: Neodymium magnets can ruin payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
Power loss in heat
Regular neodymium magnets (N-type) undergo demagnetization when the temperature goes above 80°C. This process is irreversible.
Magnetic interference
Be aware: neodymium magnets produce a field that confuses precision electronics. Maintain a separation from your phone, device, and GPS.
Risk of cracking
Watch out for shards. Magnets can fracture upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.
No play value
Only for adults. Small elements can be swallowed, leading to intestinal necrosis. Store out of reach of kids and pets.
ICD Warning
For implant holders: Powerful magnets affect electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
Flammability
Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.
Warning for allergy sufferers
Medical facts indicate that nickel (the usual finish) is a strong allergen. If you have an allergy, avoid direct skin contact and select encased magnets.
Bodily injuries
Large magnets can smash fingers instantly. Do not put your hand betwixt two attracting surfaces.
Caution required
Before use, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
