Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
- Magnets very well resist against demagnetization caused by foreign field sources,
- In other words, due to the metallic finish of silver, the element gains visual value,
- The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
- 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 modularity in forming and the ability to adapt to specific needs,
- Huge importance in modern technologies – they are used in HDD drives, electric drive systems, diagnostic systems, as well as technologically advanced constructions.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Weaknesses
- At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their strength 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 stability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complicated forms in magnets, we recommend using cover - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small components of these magnets can be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- with a thickness minimum 10 mm
- with a plane perfectly flat
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction vertical to the plane
- in temp. approx. 20°C
Determinants of practical lifting force of a magnet
- Clearance – existence of any layer (paint, tape, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin sheet does not accept the full field, causing part of the power to be lost into the air.
- Steel type – low-carbon steel gives the best results. Alloy admixtures lower magnetic properties and lifting capacity.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate reduces the load capacity.
Warnings
Bodily injuries
Big blocks can break fingers instantly. Never put your hand between two strong magnets.
Implant safety
People with a heart stimulator have to maintain an safe separation from magnets. The magnetic field can disrupt the operation of the life-saving device.
Maximum temperature
Standard neodymium magnets (grade N) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Safe distance
Data protection: Neodymium magnets can damage payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Flammability
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Beware of splinters
Neodymium magnets are ceramic materials, meaning they are prone to chipping. Collision of two magnets will cause them cracking into small pieces.
GPS and phone interference
Remember: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your mobile, device, and GPS.
Product not for children
Neodymium magnets are not suitable for play. Swallowing several magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and requires immediate surgery.
Allergy Warning
A percentage of the population experience a sensitization to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching might lead to skin redness. We strongly advise use protective gloves.
Caution required
Handle magnets consciously. Their powerful strength can shock even professionals. Be vigilant and do not underestimate their power.
