Pros and cons of Nd2Fe14B magnets.
Advantages
- They retain full power for almost 10 years – the loss is just ~1% (based on simulations),
- They feature excellent resistance to magnetism drop due to external fields,
- In other words, due to the aesthetic surface of silver, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to versatility in forming and the capacity to modify to specific needs,
- Versatile presence in modern industrial fields – they are used in computer drives, brushless drives, medical devices, also complex engineering applications.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Cons
- At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets experience a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and 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. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complex forms in magnets, we recommend using a housing - magnetic mechanism.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Additionally, tiny parts of these magnets are able to complicate diagnosis medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- on a plate made of structural steel, optimally conducting the magnetic flux
- with a thickness minimum 10 mm
- with an ground contact surface
- with direct contact (no coatings)
- during detachment in a direction perpendicular to the mounting surface
- in neutral thermal conditions
Lifting capacity in practice – influencing factors
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Steel type – low-carbon steel gives the best results. Higher carbon content reduce magnetic properties and holding force.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces reduce efficiency.
- Thermal environment – heating the magnet results in weakening of induction. Check the maximum operating temperature for a given model.
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Caution required
Handle magnets consciously. Their immense force can shock even experienced users. Plan your moves and do not underestimate their power.
Safe distance
Device Safety: Strong magnets can damage payment cards and sensitive devices (heart implants, medical aids, mechanical watches).
Dust explosion hazard
Machining of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Nickel allergy
Some people experience a sensitization to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact might lead to skin redness. We recommend wear protective gloves.
Implant safety
Health Alert: Strong magnets can turn off heart devices and defibrillators. Do not approach if you have medical devices.
Thermal limits
Standard neodymium magnets (grade N) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
Crushing risk
Big blocks can crush fingers instantly. Under no circumstances put your hand between two strong magnets.
Threat to navigation
A strong magnetic field disrupts the functioning of compasses in phones and GPS navigation. Keep magnets near a device to avoid damaging the sensors.
Magnet fragility
Neodymium magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets leads to them shattering into shards.
Do not give to children
Neodymium magnets are not suitable for play. Accidental ingestion of a few magnets may result in them pinching intestinal walls, which poses a critical condition and requires immediate surgery.
