Pros and cons of neodymium magnets.
Pros
- They have stable power, and over around ten years their performance decreases symbolically – ~1% (in testing),
- Neodymium magnets prove to be highly resistant to magnetic field loss caused by external field sources,
- In other words, due to the smooth finish of nickel, the element gains visual value,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of individual machining as well as adapting to precise needs,
- Fundamental importance in future technologies – they find application in HDD drives, electromotive mechanisms, precision medical tools, as well as modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Limitations
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in realizing threads and complicated forms in magnets, we propose using cover - magnetic holder.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. Additionally, small components of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- Due to neodymium price, their price exceeds standard values,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what contributes to it?
- using a base made of mild steel, functioning as a circuit closing element
- whose thickness equals approx. 10 mm
- with a plane cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- during detachment in a direction vertical to the plane
- at ambient temperature room level
Impact of factors on magnetic holding capacity in practice
- Air gap (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Angle of force application – highest force is available only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material type – ideal substrate is pure iron steel. Cast iron may attract less.
- Surface quality – the smoother and more polished the plate, the better the adhesion and higher the lifting capacity. Unevenness acts like micro-gaps.
- Operating temperature – neodymium magnets have a negative temperature coefficient. At higher temperatures they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the lifting capacity.
Warnings
Eye protection
NdFeB magnets are sintered ceramics, which means they are prone to chipping. Collision of two magnets will cause them breaking into shards.
Demagnetization risk
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. Damage is permanent.
Danger to the youngest
NdFeB magnets are not intended for children. Eating several magnets can lead to them connecting inside the digestive tract, which constitutes a critical condition and necessitates urgent medical intervention.
Dust is flammable
Mechanical processing of neodymium magnets poses a fire risk. Magnetic powder reacts violently with oxygen and is difficult to extinguish.
Danger to pacemakers
People with a heart stimulator must maintain an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.
Hand protection
Watch your fingers. Two large magnets will join instantly with a force of massive weight, destroying anything in their path. Exercise extreme caution!
Skin irritation risks
Nickel alert: The nickel-copper-nickel coating consists of nickel. If an allergic reaction appears, cease handling magnets and use protective gear.
Safe distance
Equipment safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, timepieces).
GPS Danger
A strong magnetic field interferes with the operation of compasses in smartphones and navigation systems. Maintain magnets near a smartphone to avoid breaking the sensors.
Safe operation
Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or hurt your hand. Think ahead.
