Pros and cons of neodymium magnets.
Benefits
- They retain attractive force for around 10 years – the loss is just ~1% (according to analyses),
- Neodymium magnets are exceptionally resistant to demagnetization caused by external magnetic fields,
- Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold-plated, or silver-plated gives an modern appearance,
- Magnets are distinguished by extremely high magnetic induction on the outer side,
- Neodymium magnets are characterized by very 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...
- Thanks to the possibility of free molding and customization to specialized requirements, magnetic components can be modeled in a wide range of geometric configurations, which increases their versatility,
- Fundamental importance in modern industrial fields – they are used in data components, electric drive systems, medical equipment, as well as complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in compact constructions
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also increases their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 very resistant to heat
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
- Limited possibility of producing nuts in the magnet and complicated shapes - preferred is cover - magnetic holder.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these products are able to complicate diagnosis medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Magnetic strength at its maximum – what it depends on?
- using a plate made of mild steel, serving as a ideal flux conductor
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a plane perfectly flat
- with total lack of distance (no coatings)
- for force applied 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 dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
- Plate thickness – insufficiently thick sheet does not accept the full field, causing part of the power to be wasted to the other side.
- Plate material – mild steel gives the best results. Higher carbon content reduce magnetic properties and lifting capacity.
- Base smoothness – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the holding force is lower. Moreover, even a small distance between the magnet and the plate reduces the holding force.
Precautions when working with NdFeB magnets
Phone sensors
Note: rare earth magnets generate a field that confuses precision electronics. Maintain a safe distance from your phone, device, and navigation systems.
Risk of cracking
Protect your eyes. Magnets can fracture upon violent connection, ejecting shards into the air. Wear goggles.
Crushing risk
Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Allergic reactions
Studies show that nickel (standard magnet coating) is a potent allergen. If you have an allergy, refrain from direct skin contact or select coated magnets.
Adults only
Always keep magnets out of reach of children. Risk of swallowing is high, and the effects of magnets connecting inside the body are fatal.
Permanent damage
Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.
Fire warning
Fire hazard: Neodymium dust is explosive. Do not process magnets without safety gear as this may cause fire.
Respect the power
Exercise caution. Neodymium magnets attract from a long distance and connect with massive power, often quicker than you can move away.
Threat to electronics
Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Life threat
Patients with a ICD must keep an absolute distance from magnets. The magnetism can disrupt the functioning of the implant.
