Pros and cons of Nd2Fe14B magnets.
Benefits
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (in testing),
- Magnets perfectly resist against loss of magnetization caused by foreign field sources,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- They show high magnetic induction at the operating surface, which increases their power,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Thanks to flexibility in forming and the capacity to customize to client solutions,
- Key role in advanced technology sectors – they are commonly used in data components, electromotive mechanisms, medical devices, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in miniature devices
Limitations
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing threads in the magnet and complicated forms - preferred is cover - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, if swallowed, which is particularly important in the context of child health protection. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price exceeds standard values,
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what affects it?
- with the application of a yoke made of special test steel, ensuring full magnetic saturation
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- with an polished touching surface
- with total lack of distance (no paint)
- under perpendicular force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Distance – the presence of any layer (paint, tape, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
- Surface finish – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Temperature – temperature increase results in weakening of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the holding force.
Safety rules for work with NdFeB magnets
Magnetic interference
A strong magnetic field disrupts the operation of magnetometers in smartphones and navigation systems. Do not bring magnets close to a device to avoid breaking the sensors.
Respect the power
Use magnets consciously. Their huge power can shock even experienced users. Be vigilant and respect their power.
Flammability
Machining of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Magnets are brittle
NdFeB magnets are ceramic materials, which means they are very brittle. Impact of two magnets will cause them cracking into shards.
Finger safety
Risk of injury: The attraction force is so immense that it can cause blood blisters, pinching, and broken bones. Use thick gloves.
Magnetic media
Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (pacemakers, hearing aids, timepieces).
Swallowing risk
Always store magnets away from children. Risk of swallowing is high, and the effects of magnets connecting inside the body are very dangerous.
Warning for heart patients
Warning for patients: Powerful magnets affect medical devices. Maintain minimum 30 cm distance or request help to work with the magnets.
Do not overheat magnets
Control the heat. Exposing the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Allergy Warning
Nickel alert: The Ni-Cu-Ni coating contains nickel. If skin irritation occurs, cease working with magnets and use protective gear.
