Advantages and disadvantages of neodymium magnets.
Pros
- They have constant strength, and over around ten years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets are distinguished by highly resistant to demagnetization caused by magnetic disturbances,
- A magnet with a shiny nickel surface has an effective appearance,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures approaching 230°C and above...
- Thanks to flexibility in shaping and the capacity to modify to unusual requirements,
- Fundamental importance in high-tech industry – they are commonly used in data components, drive modules, advanced medical instruments, and multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in miniature devices
Cons
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also increases their durability
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, when using outdoors
- Limited possibility of making nuts in the magnet and complex forms - preferred is a housing - mounting mechanism.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these devices are able to be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Magnetic strength at its maximum – what it depends on?
- using a sheet made of high-permeability steel, acting as a circuit closing element
- whose transverse dimension reaches at least 10 mm
- with an ground contact surface
- without the slightest air gap between the magnet and steel
- under axial application of breakaway force (90-degree angle)
- at room temperature
Determinants of practical lifting force of a magnet
- Distance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick plate does not accept the full field, causing part of the power to be escaped into the air.
- Plate material – mild steel gives the best results. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, however under parallel forces the load capacity is reduced by as much as fivefold. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Threat to electronics
Device Safety: Strong magnets can damage payment cards and delicate electronics (heart implants, hearing aids, timepieces).
Health Danger
Medical warning: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
GPS Danger
An intense magnetic field negatively affects the operation of compasses in phones and navigation systems. Keep magnets near a device to avoid breaking the sensors.
Product not for children
These products are not toys. Accidental ingestion of multiple magnets may result in them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
Material brittleness
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Clashing of two magnets will cause them shattering into small pieces.
Bone fractures
Big blocks can crush fingers in a fraction of a second. Never put your hand betwixt two strong magnets.
Allergic reactions
Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, immediately stop working with magnets and wear gloves.
Do not underestimate power
Before starting, read the rules. Uncontrolled attraction can destroy the magnet or injure your hand. Be predictive.
Heat sensitivity
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Machining danger
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
