Pros as well as cons of Nd2Fe14B magnets.
Strengths
- They do not lose strength, even after nearly ten years – the decrease in strength is only ~1% (theoretically),
- Magnets effectively resist against loss of magnetization caused by foreign field sources,
- In other words, due to the metallic surface of gold, the element gains visual value,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the possibility of precise forming and adaptation to specialized needs, magnetic components can be produced in a broad palette of forms and dimensions, which expands the range of possible applications,
- Huge importance in modern industrial fields – they are commonly used in HDD drives, drive modules, advanced medical instruments, as well as multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- We recommend a housing - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
- Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these devices can complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which can limit application in large quantities
Holding force characteristics
Maximum lifting force for a neodymium magnet – what affects it?
- with the contact of a sheet made of low-carbon steel, guaranteeing maximum field concentration
- possessing a massiveness of min. 10 mm to avoid saturation
- with an ideally smooth touching surface
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (in the magnet axis)
- at room temperature
Key elements affecting lifting force
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by varnish or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Plate texture – ground elements ensure maximum contact, which increases force. Rough surfaces weaken the grip.
- Temperature – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Fire risk
Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Fragile material
Neodymium magnets are ceramic materials, which means they are very brittle. Impact of two magnets will cause them cracking into shards.
Do not underestimate power
Use magnets consciously. Their immense force can surprise even professionals. Be vigilant and do not underestimate their force.
Warning for heart patients
Patients with a heart stimulator must keep an safe separation from magnets. The magnetic field can stop the functioning of the life-saving device.
Bone fractures
Large magnets can crush fingers instantly. Never put your hand betwixt two attracting surfaces.
Do not give to children
These products are not suitable for play. Eating multiple magnets can lead to them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.
Allergy Warning
Certain individuals experience a sensitization to nickel, which is the standard coating for NdFeB magnets. Prolonged contact can result in a rash. It is best to wear protective gloves.
Threat to navigation
Navigation devices and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the internal compass in your phone.
Demagnetization risk
Watch the temperature. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Cards and drives
Very strong magnetic fields can erase data on credit cards, hard drives, and storage devices. Keep a distance of at least 10 cm.
