Strengths and weaknesses of neodymium magnets.
Strengths
- They have unchanged lifting capacity, and over more than 10 years their attraction force decreases symbolically – ~1% (in testing),
- Magnets perfectly defend themselves against demagnetization caused by foreign field sources,
- In other words, due to the smooth layer of gold, the element is aesthetically pleasing,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the potential of flexible shaping and adaptation to custom projects, magnetic components can be produced in a variety of shapes and sizes, which makes them more universal,
- Universal use in modern industrial fields – they serve a role in computer drives, electromotive mechanisms, advanced medical instruments, as well as other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which allows their use in small systems
Weaknesses
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also increases their durability
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Due to limitations in creating nuts and complicated forms in magnets, we recommend using cover - magnetic holder.
- Potential hazard to health – tiny shards of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Maximum magnetic pulling force – what affects it?
- on a block made of mild steel, effectively closing the magnetic flux
- whose thickness is min. 10 mm
- characterized by lack of roughness
- with total lack of distance (no impurities)
- under perpendicular force direction (90-degree angle)
- at room temperature
Determinants of practical lifting force of a magnet
- Air gap (between the magnet and the plate), because even a very small distance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, corrosion or debris).
- Loading method – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Steel type – mild steel gives the best results. Alloy admixtures decrease magnetic properties and lifting capacity.
- Surface quality – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined using a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the holding force.
Warnings
Serious injuries
Pinching hazard: The pulling power is so great that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
Heat sensitivity
Watch the temperature. Exposing the magnet above 80 degrees Celsius will ruin its properties and strength.
Threat to electronics
Intense magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Maintain a gap of min. 10 cm.
Skin irritation risks
Allergy Notice: The Ni-Cu-Ni coating consists of nickel. If redness occurs, cease handling magnets and use protective gear.
Impact on smartphones
Be aware: rare earth magnets generate a field that disrupts sensitive sensors. Keep a separation from your phone, tablet, and GPS.
Eye protection
Despite the nickel coating, neodymium is brittle and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Caution required
Handle with care. Rare earth magnets attract from a distance and connect with massive power, often quicker than you can move away.
Fire risk
Dust created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Health Danger
People with a ICD must maintain an safe separation from magnets. The magnetic field can disrupt the operation of the life-saving device.
No play value
Adult use only. Tiny parts can be swallowed, leading to serious injuries. Keep away from children and animals.
