Advantages and disadvantages of neodymium magnets.
Advantages
- Their strength is maintained, and after around 10 years it decreases only by ~1% (theoretically),
- Neodymium magnets prove to be extremely resistant to magnetic field loss caused by magnetic disturbances,
- Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold, or silver-plated gives an clean appearance,
- Magnets have extremely high magnetic induction on the active area,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Thanks to modularity in forming and the capacity to modify to client solutions,
- Key role in advanced technology sectors – they are utilized in magnetic memories, electromotive mechanisms, medical devices, and industrial machines.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- At strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, in case of application outdoors
- We recommend a housing - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. Additionally, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- with a thickness minimum 10 mm
- with a plane cleaned and smooth
- without any clearance between the magnet and steel
- during pulling in a direction vertical to the plane
- in stable room temperature
Key elements affecting lifting force
- Clearance – existence of any layer (rust, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Load vector – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the lifting capacity (the magnet "punches through" it).
- Material composition – different alloys reacts the same. High carbon content worsen the attraction effect.
- Surface finish – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was measured 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 5 times. Moreover, even a minimal clearance between the magnet’s surface and the plate reduces the holding force.
Warnings
Medical implants
Life threat: Neodymium magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Crushing risk
Pinching hazard: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
Product not for children
Only for adults. Small elements pose a choking risk, leading to severe trauma. Keep out of reach of kids and pets.
Eye protection
Despite metallic appearance, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.
Machining danger
Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.
Compass and GPS
Be aware: neodymium magnets produce a field that confuses precision electronics. Keep a safe distance from your phone, device, and GPS.
Skin irritation risks
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, immediately stop working with magnets and use protective gear.
Cards and drives
Do not bring magnets near a wallet, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Powerful field
Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Think ahead.
Operating temperature
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will ruin its properties and pulling force.
