Strengths as well as weaknesses of Nd2Fe14B magnets.
Strengths
- They have constant strength, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
- They feature excellent resistance to magnetic field loss due to external fields,
- A magnet with a shiny nickel surface looks better,
- Neodymium magnets generate maximum magnetic induction on a their surface, which increases force concentration,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of exact shaping as well as modifying to atypical conditions,
- Wide application in advanced technology sectors – they find application in HDD drives, electric drive systems, precision medical tools, also other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their 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.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of producing nuts in the magnet and complex shapes - recommended is cover - mounting mechanism.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the context of child health protection. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Maximum holding power of the magnet – what contributes to it?
- using a plate made of mild steel, acting as a magnetic yoke
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by smoothness
- without the slightest air gap between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- in stable room temperature
Impact of factors on magnetic holding capacity in practice
- Gap (between the magnet and the metal), as even a very small distance (e.g. 0.5 mm) leads to a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Base massiveness – too thin plate does not close the flux, causing part of the flux to be lost into the air.
- Material composition – different alloys reacts the same. Alloy additives worsen the attraction effect.
- Smoothness – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the holding force.
Safety rules for work with NdFeB magnets
Fragile material
Despite the nickel coating, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Crushing force
Risk of injury: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Protective gloves are recommended.
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Dust is flammable
Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.
Medical implants
Warning for patients: Strong magnetic fields affect electronics. Maintain at least 30 cm distance or ask another person to work with the magnets.
Nickel allergy
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If skin irritation occurs, cease handling magnets and wear gloves.
Heat warning
Do not overheat. NdFeB magnets are susceptible to temperature. If you require resistance above 80°C, inquire about HT versions (H, SH, UH).
GPS Danger
Navigation devices and mobile phones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Safe distance
Very strong magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.
Do not give to children
Absolutely store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets connecting inside the body are tragic.
