Pros and cons of neodymium magnets.
Benefits
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (based on calculations),
- Neodymium magnets prove to be exceptionally resistant to demagnetization caused by external magnetic fields,
- In other words, due to the glossy finish of gold, the element becomes visually attractive,
- Magnetic induction on the top side of the magnet remains impressive,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling action at temperatures approaching 230°C and above...
- Thanks to modularity in designing and the capacity to modify to specific needs,
- Fundamental importance in innovative solutions – they find application in mass storage devices, electric drive systems, diagnostic systems, also multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, occupying minimum space,
Limitations
- 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 power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We suggest a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complex forms.
- Possible danger resulting from small fragments of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, small elements of these products can complicate diagnosis medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a plate made of mild steel, functioning as a ideal flux conductor
- whose thickness is min. 10 mm
- with a plane perfectly flat
- with zero gap (no coatings)
- during pulling in a direction vertical to the plane
- at temperature approx. 20 degrees Celsius
Determinants of practical lifting force of a magnet
- Distance – the presence of any layer (rust, dirt, gap) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is obtained only during pulling at a 90° angle. The shear force of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface finish – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Heat – neodymium magnets have a negative temperature coefficient. At higher temperatures they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was measured using a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the holding force is lower. Additionally, even a slight gap between the magnet and the plate lowers the load capacity.
Precautions when working with NdFeB magnets
Nickel allergy
Allergy Notice: The nickel-copper-nickel coating contains nickel. If redness appears, immediately stop working with magnets and use protective gear.
Mechanical processing
Dust produced during machining of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Do not underestimate power
Use magnets with awareness. Their huge power can shock even experienced users. Plan your moves and respect their force.
Magnetic media
Do not bring magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and erase data from cards.
Operating temperature
Standard neodymium magnets (N-type) undergo demagnetization when the temperature surpasses 80°C. Damage is permanent.
Adults only
Only for adults. Small elements pose a choking risk, leading to intestinal necrosis. Store out of reach of children and animals.
GPS Danger
Remember: rare earth magnets produce a field that confuses sensitive sensors. Keep a separation from your mobile, tablet, and GPS.
Bodily injuries
Big blocks can smash fingers instantly. Never place your hand between two attracting surfaces.
Protective goggles
Despite metallic appearance, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Medical interference
People with a heart stimulator should keep an large gap from magnets. The magnetism can disrupt the operation of the implant.
