Advantages and disadvantages of neodymium magnets.
Strengths
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
- They possess excellent resistance to magnetism drop when exposed to opposing magnetic fields,
- A magnet with a smooth nickel surface is more attractive,
- Magnets are characterized by excellent magnetic induction on the surface,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of individual modeling as well as adjusting to individual applications,
- Versatile presence in modern industrial fields – they are used in data components, motor assemblies, diagnostic systems, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in compact constructions
Weaknesses
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose 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 start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of creating threads in the magnet and complicated shapes - preferred is casing - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which becomes key in the context of child safety. Additionally, small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
- With budget limitations the cost of neodymium magnets can be a barrier,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a sheet made of high-permeability steel, acting as a ideal flux conductor
- with a cross-section minimum 10 mm
- characterized by even structure
- with zero gap (without paint)
- during pulling in a direction vertical to the mounting surface
- at temperature room level
Magnet lifting force in use – key factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Hardened steels may attract less.
- Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal environment – temperature increase causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was carried out on a smooth plate of suitable thickness, under perpendicular forces, whereas under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Do not give to children
Neodymium magnets are not intended for children. Accidental ingestion of a few magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and requires immediate surgery.
Keep away from computers
Avoid bringing magnets close to a wallet, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Medical implants
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Precision electronics
Navigation devices and smartphones are highly susceptible to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the internal compass in your phone.
Skin irritation risks
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease handling magnets and wear gloves.
Physical harm
Pinching hazard: The attraction force is so great that it can result in blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Handling rules
Handle with care. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can move away.
Fire warning
Machining of NdFeB material poses a fire risk. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Heat sensitivity
Control the heat. Heating the magnet above 80 degrees Celsius will permanently weaken its properties and strength.
Magnet fragility
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
