Advantages as well as disadvantages of neodymium magnets.
Strengths
- They retain magnetic properties for nearly ten years – the loss is just ~1% (according to analyses),
- Magnets effectively defend themselves against demagnetization caused by ambient magnetic noise,
- A magnet with a smooth gold surface is more attractive,
- Magnetic induction on the working part of the magnet is maximum,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the option of flexible shaping and adaptation to specialized needs, neodymium magnets can be produced in a variety of geometric configurations, which amplifies use scope,
- Key role in high-tech industry – they serve a role in computer drives, brushless drives, diagnostic systems, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which enables their usage in miniature devices
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend casing - magnetic holder, due to difficulties in producing nuts inside the magnet and complex shapes.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to disrupt the diagnostic process medical in case of swallowing.
- With large orders the cost of neodymium magnets can be a barrier,
Lifting parameters
Maximum holding power of the magnet – what affects it?
- with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a thickness of at least 10 mm
- with an ideally smooth contact surface
- without the slightest insulating layer between the magnet and steel
- under axial force direction (90-degree angle)
- at standard ambient temperature
Lifting capacity in real conditions – factors
- Air gap (betwixt the magnet and the metal), since even a very small clearance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, rust or dirt).
- Angle of force application – maximum parameter is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is standardly several times smaller (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick steel does not accept the full field, causing part of the flux to be lost into the air.
- Steel grade – the best choice is high-permeability steel. Hardened steels may have worse magnetic properties.
- Surface finish – full contact is possible only on smooth steel. Rough texture create air cushions, reducing force.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Lifting capacity was measured using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Danger to pacemakers
Patients with a ICD should maintain an absolute distance from magnets. The magnetic field can interfere with the operation of the implant.
Physical harm
Large magnets can break fingers in a fraction of a second. Never place your hand between two strong magnets.
Magnet fragility
Neodymium magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them breaking into small pieces.
Heat warning
Avoid heat. NdFeB magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Handling guide
Use magnets consciously. Their huge power can surprise even experienced users. Be vigilant and respect their power.
Warning for allergy sufferers
A percentage of the population experience a hypersensitivity to nickel, which is the typical protective layer for neodymium magnets. Extended handling can result in dermatitis. We strongly advise wear protective gloves.
Keep away from electronics
Navigation devices and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Electronic devices
Avoid bringing magnets close to a purse, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
Product not for children
NdFeB magnets are not intended for children. Eating several magnets can lead to them pinching intestinal walls, which poses a direct threat to life and necessitates urgent medical intervention.
Combustion hazard
Dust created during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.
