Advantages as well as disadvantages of Nd2Fe14B magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They do not lose their magnetic properties even under strong external field,
- The use of an aesthetic finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets achieve maximum magnetic induction on a small surface, which allows for strong attraction,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the form) even at a temperature of 230°C or more...
- Possibility of detailed shaping as well as modifying to complex requirements,
- Wide application in innovative solutions – they are utilized in hard drives, drive modules, advanced medical instruments, also industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions
Cons
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- Neodymium magnets decrease their power 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 durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing nuts in the magnet and complicated forms - recommended is a housing - mounting mechanism.
- Health risk to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these products 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
Lifting parameters
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a base made of mild steel, acting as a magnetic yoke
- possessing a massiveness of minimum 10 mm to ensure full flux closure
- characterized by smoothness
- under conditions of gap-free contact (surface-to-surface)
- under axial application of breakaway force (90-degree angle)
- in temp. approx. 20°C
Practical aspects of lifting capacity – factors
- Space between magnet and steel – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Load vector – maximum parameter is available only during perpendicular pulling. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Plate thickness – too thin sheet causes magnetic saturation, causing part of the flux to be escaped to the other side.
- Steel grade – ideal substrate is pure iron steel. Cast iron may attract less.
- Surface quality – the more even the plate, the better the adhesion and stronger the hold. Roughness acts like micro-gaps.
- Thermal factor – hot environment weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Serious injuries
Risk of injury: The attraction force is so immense that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Data carriers
Data protection: Strong magnets can damage payment cards and delicate electronics (heart implants, medical aids, mechanical watches).
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness happens, cease handling magnets and wear gloves.
Do not overheat magnets
Keep cool. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, look for special high-temperature series (H, SH, UH).
Risk of cracking
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets leads to them breaking into small pieces.
Machining danger
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
No play value
Strictly keep magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are life-threatening.
Implant safety
Individuals with a ICD should keep an large gap from magnets. The magnetism can interfere with the operation of the implant.
Conscious usage
Use magnets consciously. Their powerful strength can surprise even professionals. Be vigilant and do not underestimate their power.
Phone sensors
A powerful magnetic field interferes with the operation of magnetometers in smartphones and navigation systems. Do not bring magnets near a device to prevent breaking the sensors.
