Strengths and weaknesses of rare earth magnets.
Strengths
- They do not lose magnetism, even during nearly ten years – the decrease in lifting capacity is only ~1% (based on measurements),
- They are extremely resistant to demagnetization induced by external disturbances,
- A magnet with a metallic silver surface has an effective appearance,
- Magnets are distinguished by excellent magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Due to the potential of free molding and customization to specialized projects, NdFeB magnets can be modeled in a variety of forms and dimensions, which makes them more universal,
- Huge importance in modern technologies – they are utilized in computer drives, motor assemblies, medical equipment, and other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Weaknesses
- They are fragile upon heavy 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
- 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 stability 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 making threads in the magnet and complex forms - recommended is casing - magnetic holder.
- Health risk related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, small components of these magnets can be problematic in diagnostics medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
- possessing a massiveness of at least 10 mm to avoid saturation
- characterized by even structure
- without any clearance 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
- Clearance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Thermal conditions – neodymium magnets have a negative temperature coefficient. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was measured with the use of a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.
Safe handling of NdFeB magnets
Health Danger
Individuals with a heart stimulator must maintain an absolute distance from magnets. The magnetic field can interfere with the operation of the implant.
Power loss in heat
Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.
Crushing force
Big blocks can crush fingers instantly. Never put your hand between two strong magnets.
Keep away from children
NdFeB magnets are not toys. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which constitutes a severe health hazard and requires immediate surgery.
Mechanical processing
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets in home conditions as this may cause fire.
Precision electronics
Navigation devices and smartphones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Allergic reactions
A percentage of the population experience a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Frequent touching might lead to dermatitis. It is best to wear safety gloves.
Safe distance
Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Eye protection
Protect your eyes. Magnets can fracture upon uncontrolled impact, launching shards into the air. We recommend safety glasses.
Powerful field
Be careful. Rare earth magnets attract from a distance and snap with huge force, often faster than you can react.
