Advantages as well as disadvantages of neodymium magnets.
Strengths
- They do not lose magnetism, even after approximately ten years – the reduction in lifting capacity is only ~1% (according to tests),
- Neodymium magnets prove to be remarkably resistant to loss of magnetic properties caused by external magnetic fields,
- In other words, due to the aesthetic finish of silver, the element looks attractive,
- The surface of neodymium magnets generates a strong magnetic field – this is one of their assets,
- 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...
- Considering the ability of flexible molding and adaptation to unique needs, neodymium magnets can be manufactured in a variety of shapes and sizes, which makes them more universal,
- Fundamental importance in modern industrial fields – they are commonly used in magnetic memories, electric drive systems, diagnostic systems, as well as industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in small systems
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects 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.
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation as well as corrosion.
- Limited ability of making threads in the magnet and complex shapes - recommended is casing - magnet mounting.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Additionally, small elements of these magnets can complicate diagnosis medical after entering the body.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum magnetic pulling force – what affects it?
- using a sheet made of high-permeability steel, serving as a ideal flux conductor
- whose thickness is min. 10 mm
- characterized by lack of roughness
- with total lack of distance (no coatings)
- during pulling in a direction perpendicular to the plane
- at standard ambient temperature
Key elements affecting lifting force
- Distance (betwixt the magnet and the metal), as even a microscopic clearance (e.g. 0.5 mm) can cause a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Steel type – low-carbon steel attracts best. Alloy steels decrease magnetic permeability and lifting capacity.
- Surface structure – the more even the plate, the better the adhesion and stronger the hold. Roughness creates an air distance.
- Heat – neodymium magnets have a negative temperature coefficient. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet’s surface and the plate lowers the holding force.
Safe handling of neodymium magnets
Sensitization to coating
Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, cease working with magnets and wear gloves.
Adults only
Adult use only. Tiny parts pose a choking risk, causing serious injuries. Store out of reach of children and animals.
Health Danger
Patients with a ICD have to maintain an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
Permanent damage
Keep cool. NdFeB magnets are sensitive to temperature. If you need resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Respect the power
Handle magnets with awareness. Their huge power can surprise even experienced users. Stay alert and do not underestimate their force.
Keep away from electronics
Be aware: neodymium magnets produce a field that confuses precision electronics. Keep a separation from your mobile, device, and navigation systems.
Machining danger
Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Keep away from computers
Do not bring magnets close to a wallet, laptop, or TV. The magnetism can destroy these devices and wipe information from cards.
Bodily injuries
Big blocks can crush fingers instantly. Never put your hand between two attracting surfaces.
Protective goggles
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Impact of two magnets leads to them shattering into small pieces.
