Advantages and disadvantages of Nd2Fe14B magnets.
Strengths
- Their strength is durable, and after around 10 years it decreases only by ~1% (according to research),
- They possess excellent resistance to magnetic field loss due to external fields,
- By applying a smooth coating of nickel, the element presents an elegant look,
- Magnets are distinguished by very high magnetic induction on the surface,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Thanks to versatility in designing and the capacity to customize to client solutions,
- Significant place in modern technologies – they are utilized in magnetic memories, electric motors, diagnostic systems, as well as multitasking production systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage and 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in producing threads and complex shapes in magnets, we propose using a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that small components of these devices 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
Pull force analysis
Maximum lifting capacity of the magnet – what contributes to it?
- on a plate made of structural steel, perfectly concentrating the magnetic field
- with a thickness of at least 10 mm
- characterized by smoothness
- under conditions of gap-free contact (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at room temperature
Impact of factors on magnetic holding capacity in practice
- Space between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Direction of force – highest force is reached only during perpendicular pulling. The shear force of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – mild steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
- Thermal environment – temperature increase results in weakening of force. It is worth remembering the maximum operating temperature for a given model.
Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate reduces the lifting capacity.
Precautions when working with NdFeB magnets
Medical implants
Patients with a ICD should maintain an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.
This is not a toy
These products are not toys. Eating a few magnets may result in them attracting across intestines, which poses a direct threat to life and necessitates immediate surgery.
Finger safety
Risk of injury: The pulling power is so immense that it can cause hematomas, crushing, and even bone fractures. Use thick gloves.
Material brittleness
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets leads to them cracking into small pieces.
Warning for allergy sufferers
Medical facts indicate that the nickel plating (standard magnet coating) is a potent allergen. If your skin reacts to metals, refrain from direct skin contact or select versions in plastic housing.
Data carriers
Powerful magnetic fields can corrupt files on credit cards, hard drives, and other magnetic media. Keep a distance of min. 10 cm.
Demagnetization risk
Keep cool. NdFeB magnets are susceptible to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Fire risk
Drilling and cutting of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Conscious usage
Be careful. Rare earth magnets attract from a distance and snap with huge force, often faster than you can react.
Threat to navigation
A strong magnetic field disrupts the operation of compasses in smartphones and navigation systems. Keep magnets near a smartphone to prevent damaging the sensors.
