Pros and cons of neodymium magnets.
Benefits
- Their strength is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
- They feature excellent resistance to magnetism drop due to opposing magnetic fields,
- By using a lustrous layer of silver, the element has an proper look,
- Magnets have very high magnetic induction on the outer side,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- In view of the potential of precise molding and customization to specialized needs, NdFeB magnets can be modeled in a wide range of shapes and sizes, which increases their versatility,
- Key role in modern technologies – they are commonly used in HDD drives, drive modules, diagnostic systems, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in miniature devices
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures 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 threads and complicated forms in magnets, we propose using a housing - magnetic mechanism.
- Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Additionally, small components of these devices can be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Holding force characteristics
Maximum magnetic pulling force – what contributes to it?
- with the use of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- possessing a massiveness of min. 10 mm to ensure full flux closure
- with a plane free of scratches
- with total lack of distance (no impurities)
- under vertical force vector (90-degree angle)
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Distance – the presence of any layer (rust, tape, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – insufficiently thick steel does not close the flux, causing part of the flux to be lost into the air.
- Plate material – low-carbon steel attracts best. Alloy admixtures reduce magnetic properties and lifting capacity.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost they can be stronger (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Safe handling of neodymium magnets
Immense force
Use magnets with awareness. Their powerful strength can shock even professionals. Be vigilant and do not underestimate their force.
Precision electronics
Note: neodymium magnets produce a field that disrupts sensitive sensors. Keep a safe distance from your mobile, device, and navigation systems.
Bone fractures
Large magnets can break fingers instantly. Do not put your hand betwixt two strong magnets.
ICD Warning
Individuals with a heart stimulator must maintain an large gap from magnets. The magnetism can stop the operation of the life-saving device.
Swallowing risk
Product intended for adults. Small elements pose a choking risk, leading to intestinal necrosis. Store out of reach of children and animals.
Machining danger
Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Heat warning
Regular neodymium magnets (N-type) lose power when the temperature surpasses 80°C. This process is irreversible.
Protective goggles
Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Do not hit, as the magnet may shatter into hazardous fragments.
Safe distance
Intense magnetic fields can destroy records on payment cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Warning for allergy sufferers
Certain individuals have a hypersensitivity to Ni, which is the common plating for NdFeB magnets. Prolonged contact may cause dermatitis. We recommend use safety gloves.
