Advantages as well as disadvantages of neodymium magnets.
Strengths
- They do not lose strength, even during around 10 years – the reduction in lifting capacity is only ~1% (based on measurements),
- Magnets perfectly resist against demagnetization caused by foreign field sources,
- In other words, due to the metallic layer of nickel, the element is aesthetically pleasing,
- They show high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to the option of free molding and adaptation to unique requirements, neodymium magnets can be produced in a wide range of geometric configurations, which makes them more universal,
- Significant place in high-tech industry – they are used in HDD drives, electromotive mechanisms, diagnostic systems, also multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Cons
- At very strong impacts they can crack, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Due to limitations in creating threads and complicated forms in magnets, we propose using a housing - magnetic holder.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these magnets can complicate diagnosis medical when they are in the body.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum lifting capacity of the magnet – what it depends on?
- on a plate made of mild steel, optimally conducting the magnetic flux
- whose transverse dimension reaches at least 10 mm
- with a surface cleaned and smooth
- without any clearance between the magnet and steel
- under vertical force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Clearance – existence of any layer (paint, dirt, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel type – low-carbon steel attracts best. Higher carbon content reduce magnetic properties and holding force.
- Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Temperature influence – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a slight gap between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Material brittleness
Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them cracking into small pieces.
GPS and phone interference
Remember: neodymium magnets produce a field that disrupts precision electronics. Keep a separation from your phone, tablet, and navigation systems.
Health Danger
Warning for patients: Powerful magnets affect medical devices. Maintain at least 30 cm distance or ask another person to work with the magnets.
Do not underestimate power
Handle magnets consciously. Their huge power can shock even professionals. Plan your moves and do not underestimate their force.
Do not drill into magnets
Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Physical harm
Big blocks can crush fingers in a fraction of a second. Never put your hand between two strong magnets.
Permanent damage
Regular neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
Cards and drives
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, timepieces).
Choking Hazard
Product intended for adults. Small elements can be swallowed, causing serious injuries. Store away from children and animals.
Warning for allergy sufferers
Certain individuals have a sensitization to Ni, which is the standard coating for neodymium magnets. Frequent touching may cause dermatitis. We suggest use safety gloves.
