Advantages as well as disadvantages of Nd2Fe14B magnets.
Pros
- They do not lose magnetism, even over approximately ten years – the reduction in lifting capacity is only ~1% (according to tests),
- They are extremely resistant to demagnetization induced by external field influence,
- Thanks to the glossy finish, the coating of nickel, gold-plated, or silver-plated gives an modern appearance,
- Magnetic induction on the top side of the magnet is extremely intense,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, allowing for operation at temperatures reaching 230°C and above...
- Thanks to freedom in designing and the capacity to adapt to specific needs,
- Significant place in advanced technology sectors – they are used in data components, brushless drives, medical equipment, also technologically advanced constructions.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
- Neodymium magnets decrease their force 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 durability even at temperatures up to 230°C
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited possibility of producing nuts in the magnet and complicated forms - recommended is a housing - mounting mechanism.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Due to neodymium price, their price exceeds standard values,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- possessing a thickness of minimum 10 mm to avoid saturation
- with an polished touching surface
- with direct contact (no coatings)
- during pulling in a direction vertical to the mounting surface
- in stable room temperature
Practical lifting capacity: influencing factors
- Gap (betwixt the magnet and the metal), as even a microscopic distance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to paint, rust or debris).
- Loading method – catalog parameter refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (often approx. 20-30% of nominal force).
- Element thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the attraction force (the magnet "punches through" it).
- Material type – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface quality – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness acts like micro-gaps.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate decreases the load capacity.
Warnings
Avoid contact if allergic
Allergy Notice: The nickel-copper-nickel coating contains nickel. If skin irritation occurs, immediately stop handling magnets and wear gloves.
Dust explosion hazard
Fire warning: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Demagnetization risk
Control the heat. Exposing the magnet to high heat will destroy its properties and pulling force.
Medical implants
For implant holders: Powerful magnets disrupt medical devices. Keep minimum 30 cm distance or ask another person to work with the magnets.
Swallowing risk
These products are not intended for children. Accidental ingestion of multiple magnets can lead to them attracting across intestines, which poses a severe health hazard and requires urgent medical intervention.
Crushing risk
Big blocks can break fingers in a fraction of a second. Do not place your hand between two attracting surfaces.
GPS and phone interference
Be aware: neodymium magnets produce a field that disrupts precision electronics. Maintain a separation from your mobile, tablet, and navigation systems.
Safe operation
Before starting, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Electronic devices
Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Material brittleness
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
