Advantages as well as disadvantages of rare earth magnets.
Strengths
- Their magnetic field is maintained, and after around 10 years it drops only by ~1% (theoretically),
- Magnets effectively defend themselves against demagnetization caused by ambient magnetic noise,
- Thanks to the reflective finish, the layer of nickel, gold, or silver-plated gives an professional appearance,
- Magnets are distinguished by maximum magnetic induction on the outer layer,
- 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 precise forming and customization to custom solutions, neodymium magnets can be created in a broad palette of forms and dimensions, which makes them more universal,
- Huge importance in innovative solutions – they serve a role in hard drives, electric motors, diagnostic systems, and other advanced devices.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- NdFeB magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We suggest cover - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Health risk resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child safety. Furthermore, small components of these devices can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Holding force characteristics
Detachment force of the magnet in optimal conditions – what contributes to it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- with a thickness of at least 10 mm
- with a plane cleaned and smooth
- without the slightest insulating layer between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at ambient temperature room level
Magnet lifting force in use – key factors
- Distance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Angle of force application – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Steel thickness – insufficiently thick steel does not accept the full field, causing part of the power to be escaped to the other side.
- Material type – ideal substrate is high-permeability steel. Hardened steels may have worse magnetic properties.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Temperature influence – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the load capacity is reduced by as much as 75%. In addition, even a slight gap between the magnet and the plate reduces the load capacity.
Safe handling of neodymium magnets
Serious injuries
Large magnets can smash fingers in a fraction of a second. Never put your hand betwixt two attracting surfaces.
Do not give to children
Adult use only. Tiny parts can be swallowed, leading to severe trauma. Store out of reach of kids and pets.
Conscious usage
Be careful. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can react.
Fragile material
Watch out for shards. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Metal Allergy
It is widely known that the nickel plating (the usual finish) is a potent allergen. If your skin reacts to metals, avoid touching magnets with bare hands or select coated magnets.
Keep away from computers
Intense magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.
Fire risk
Drilling and cutting of neodymium magnets poses a fire hazard. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
Precision electronics
An intense magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Keep magnets near a device to prevent breaking the sensors.
Maximum temperature
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Medical implants
For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
