Pros and cons of Nd2Fe14B magnets.
Strengths
- Their power is maintained, and after approximately ten years it decreases only by ~1% (theoretically),
- Magnets very well resist against loss of magnetization caused by foreign field sources,
- A magnet with a smooth silver surface is more attractive,
- Magnets have exceptionally strong magnetic induction on the working 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 constructing and the ability to modify to individual projects,
- Wide application in high-tech industry – they are commonly used in HDD drives, drive modules, advanced medical instruments, as well as modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, with minimal size,
Cons
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only shields the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of producing threads in the magnet and complex forms - recommended is a housing - mounting mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets are able to disrupt the diagnostic process 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 affects it?
- on a plate made of structural steel, optimally conducting the magnetic field
- with a thickness no less than 10 mm
- 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 ambient temperature room level
Practical lifting capacity: influencing factors
- Clearance – existence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which reduces power rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is available only during perpendicular pulling. The force required to slide of the magnet along the surface is standardly many times lower (approx. 1/5 of the lifting capacity).
- Plate thickness – insufficiently thick plate does not accept the full field, causing part of the power to be lost to the other side.
- Steel grade – the best choice is high-permeability steel. Cast iron may attract less.
- Surface quality – the smoother and more polished the surface, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Lifting capacity was assessed by applying a polished steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate lowers the lifting capacity.
Warnings
Flammability
Combustion risk: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.
Fragile material
Despite metallic appearance, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.
This is not a toy
NdFeB magnets are not suitable for play. Accidental ingestion of multiple magnets may result in them attracting across intestines, which constitutes a severe health hazard and requires urgent medical intervention.
GPS Danger
GPS units and mobile phones are highly susceptible to magnetism. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Respect the power
Handle with care. Rare earth magnets act from a distance and connect with huge force, often quicker than you can move away.
Crushing force
Risk of injury: The attraction force is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Electronic devices
Equipment safety: Neodymium magnets can ruin data carriers and sensitive devices (heart implants, hearing aids, timepieces).
Health Danger
Medical warning: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
Maximum temperature
Do not overheat. Neodymium magnets are sensitive to heat. If you require resistance above 80°C, ask us about special high-temperature series (H, SH, UH).
Sensitization to coating
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, cease handling magnets and wear gloves.
