Pros and cons of neodymium magnets.
Strengths
- Their power is maintained, and after around ten years it decreases only by ~1% (according to research),
- Magnets effectively protect themselves against demagnetization caused by ambient magnetic noise,
- In other words, due to the smooth surface of nickel, the element looks attractive,
- They are known for high magnetic induction at the operating surface, which affects their effectiveness,
- 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...
- In view of the option of free forming and adaptation to unique projects, magnetic components can be manufactured in a wide range of forms and dimensions, which increases their versatility,
- Significant place in advanced technology sectors – they are utilized in data components, electric drive systems, diagnostic systems, also complex engineering applications.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
- We recommend cover - magnetic holder, due to difficulties in producing threads inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these magnets can complicate diagnosis medical after entering the body.
- Due to expensive raw materials, their price exceeds standard values,
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- with the use of a sheet made of special test steel, ensuring full magnetic saturation
- possessing a thickness of minimum 10 mm to ensure full flux closure
- with an polished contact surface
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (pull-off, not shear)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Space between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Steel grade – ideal substrate is pure iron steel. Cast iron may have worse magnetic properties.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under a perpendicular pulling force, however under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Precautions when working with NdFeB magnets
Eye protection
Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Medical implants
For implant holders: Strong magnetic fields disrupt electronics. Keep at least 30 cm distance or request help to handle the magnets.
Electronic devices
Do not bring magnets close to a wallet, laptop, or TV. The magnetism can permanently damage these devices and wipe information from cards.
Threat to navigation
Note: neodymium magnets generate a field that confuses precision electronics. Maintain a safe distance from your mobile, device, and navigation systems.
Avoid contact if allergic
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If skin irritation appears, immediately stop working with magnets and use protective gear.
Permanent damage
Standard neodymium magnets (grade N) undergo demagnetization when the temperature goes above 80°C. Damage is permanent.
Finger safety
Mind your fingers. Two large magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Powerful field
Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Be predictive.
No play value
Absolutely store magnets out of reach of children. Ingestion danger is significant, and the consequences of magnets clamping inside the body are tragic.
Machining danger
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
