Strengths and weaknesses of Nd2Fe14B magnets.
Strengths
- Their magnetic field remains stable, and after approximately ten years it drops only by ~1% (according to research),
- They maintain their magnetic properties even under strong external field,
- The use of an elegant layer of noble metals (nickel, gold, silver) causes the element to look better,
- Magnets are distinguished by huge magnetic induction on the active area,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to freedom in constructing and the capacity to modify to specific needs,
- Significant place in modern industrial fields – they are utilized in hard drives, brushless drives, medical devices, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems
Limitations
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as 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
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation as well as corrosion.
- We recommend cover - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
- Health risk to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. It is also worth noting that small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what it depends on?
- using a base made of high-permeability steel, functioning as a ideal flux conductor
- whose transverse dimension equals approx. 10 mm
- characterized by even structure
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in stable room temperature
Magnet lifting force in use – key factors
- Gap between magnet and steel – every millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to pulling vertically. When attempting to slide, the magnet holds significantly lower power (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – mild steel gives the best results. Alloy admixtures lower magnetic permeability and lifting capacity.
- Smoothness – ideal contact is possible only on smooth steel. Rough texture reduce the real contact area, reducing force.
- Temperature – heating the magnet results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity was assessed using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Finger safety
Danger of trauma: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.
Health Danger
People with a pacemaker must keep an absolute distance from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Allergic reactions
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands or choose encased magnets.
Keep away from electronics
An intense magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Maintain magnets close to a device to prevent breaking the sensors.
Do not underestimate power
Handle with care. Neodymium magnets attract from a long distance and snap with massive power, often quicker than you can move away.
Danger to the youngest
Only for adults. Small elements pose a choking risk, leading to serious injuries. Store away from children and animals.
Magnets are brittle
Neodymium magnets are ceramic materials, meaning they are fragile like glass. Impact of two magnets will cause them shattering into small pieces.
Fire risk
Mechanical processing of NdFeB material poses a fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Keep away from computers
Intense magnetic fields can corrupt files on payment cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Maximum temperature
Standard neodymium magnets (grade N) lose magnetization when the temperature goes above 80°C. This process is irreversible.
