Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- They are resistant to demagnetization induced by external field influence,
- Thanks to the glossy finish, the surface of nickel, gold, or silver-plated gives an professional appearance,
- Magnets are characterized by maximum magnetic induction on the outer side,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
- Thanks to modularity in constructing and the ability to modify to client solutions,
- Huge importance in modern industrial fields – they are utilized in magnetic memories, electric drive systems, medical devices, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which allows their use in small systems
Limitations
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as 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 usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited possibility of creating threads in the magnet and complicated forms - recommended is a housing - magnet mounting.
- Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the context of child health protection. Additionally, small components of these products are able to disrupt the diagnostic process medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- with the use of a sheet made of low-carbon steel, guaranteeing full magnetic saturation
- whose transverse dimension is min. 10 mm
- characterized by lack of roughness
- under conditions of no distance (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- in neutral thermal conditions
Key elements affecting lifting force
- Distance (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 paint, corrosion or debris).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Steel grade – ideal substrate is high-permeability steel. Cast iron may have worse magnetic properties.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, in contrast 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 holding force.
Warnings
Impact on smartphones
Remember: rare earth magnets produce a field that disrupts sensitive sensors. Keep a safe distance from your mobile, device, and navigation systems.
Conscious usage
Use magnets consciously. Their huge power can surprise even experienced users. Plan your moves and do not underestimate their force.
Warning for heart patients
Life threat: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have electronic implants.
Electronic devices
Device Safety: Strong magnets can damage payment cards and delicate electronics (pacemakers, medical aids, timepieces).
Magnets are brittle
Neodymium magnets are ceramic materials, which means they are very brittle. Impact of two magnets leads to them cracking into small pieces.
Skin irritation risks
Certain individuals experience a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to an allergic reaction. We suggest use safety gloves.
Machining danger
Drilling and cutting of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Product not for children
These products are not suitable for play. Eating multiple magnets can lead to them attracting across intestines, which poses a severe health hazard and requires urgent medical intervention.
Do not overheat magnets
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its properties and strength.
Hand protection
Risk of injury: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Use thick gloves.
