Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (according to theory),
- Neodymium magnets prove to be exceptionally resistant to magnetic field loss caused by magnetic disturbances,
- The use of an shiny layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnetic induction on the surface of the magnet remains maximum,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to freedom in forming and the ability to modify to client solutions,
- Huge importance in innovative solutions – they find application in data components, brushless drives, medical equipment, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in miniature devices
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only protects them against impacts but also increases their durability
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing nuts and complicated shapes in magnets, we recommend using cover - magnetic mount.
- Potential hazard related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these devices are able to be problematic in diagnostics medical in case of swallowing.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what contributes to it?
- using a base made of mild steel, functioning as a ideal flux conductor
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by smoothness
- with direct contact (no paint)
- for force acting at a right angle (in the magnet axis)
- at room temperature
Practical lifting capacity: influencing factors
- Space between magnet and steel – every 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 – highest force is reached only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is standardly many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Metal type – different alloys attracts identically. Alloy additives worsen the interaction with the magnet.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, whereas under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Dust is flammable
Drilling and cutting of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Precision electronics
GPS units and mobile phones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Keep away from computers
Do not bring magnets close to a purse, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Powerful field
Handle magnets with awareness. Their huge power can surprise even professionals. Plan your moves and respect their force.
Adults only
These products are not intended for children. Eating multiple magnets can lead to them attracting across intestines, which poses a critical condition and requires immediate surgery.
Power loss in heat
Avoid heat. NdFeB magnets are susceptible to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Fragile material
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets will cause them breaking into small pieces.
Crushing risk
Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!
Nickel allergy
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
Pacemakers
Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.
