Strengths and weaknesses of Nd2Fe14B magnets.
Advantages
- They retain full power for nearly 10 years – the drop is just ~1% (based on simulations),
- Magnets perfectly protect themselves against demagnetization caused by external fields,
- By using a decorative coating of gold, the element gains an nice look,
- Magnetic induction on the top side of the magnet is maximum,
- 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...
- Due to the possibility of flexible molding and adaptation to individualized solutions, magnetic components can be manufactured in a variety of geometric configurations, which increases their versatility,
- Huge importance in advanced technology sectors – they serve a role in HDD drives, motor assemblies, medical devices, also technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can reduce their power 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 corrode. Therefore during using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making threads in the magnet and complex forms - preferred is a housing - magnetic holder.
- Potential hazard resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small components of these magnets are able to complicate diagnosis medical after entering the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum lifting capacity of the magnet – what affects it?
- on a base made of structural steel, perfectly concentrating the magnetic field
- possessing a thickness of minimum 10 mm to avoid saturation
- characterized by lack of roughness
- without the slightest clearance between the magnet and steel
- under vertical force direction (90-degree angle)
- at standard ambient temperature
Determinants of lifting force in real conditions
- Distance – the presence of any layer (paint, tape, gap) acts as an insulator, which reduces power steeply (even by 50% at 0.5 mm).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Steel type – mild steel gives the best results. Alloy steels decrease magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Heat – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Additionally, even a small distance between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Implant safety
Individuals with a pacemaker should maintain an absolute distance from magnets. The magnetic field can stop the functioning of the implant.
Safe operation
Handle magnets with awareness. Their immense force can surprise even experienced users. Be vigilant and respect their force.
Fire risk
Drilling and cutting of neodymium magnets poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Keep away from electronics
Be aware: neodymium magnets generate a field that interferes with sensitive sensors. Keep a safe distance from your phone, device, and navigation systems.
Cards and drives
Avoid bringing magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.
No play value
These products are not toys. Swallowing multiple magnets may result in them attracting across intestines, which poses a critical condition and necessitates urgent medical intervention.
Do not overheat magnets
Regular neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Material brittleness
Neodymium magnets are sintered ceramics, meaning they are very brittle. Clashing of two magnets leads to them shattering into small pieces.
Sensitization to coating
Nickel alert: The nickel-copper-nickel coating contains nickel. If redness happens, immediately stop working with magnets and wear gloves.
Finger safety
Pinching hazard: The pulling power is so immense that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
