Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They do not lose magnetism, even over nearly 10 years – the decrease in lifting capacity is only ~1% (based on measurements),
- Neodymium magnets are distinguished by extremely resistant to loss of magnetic properties caused by external interference,
- The use of an elegant finish of noble metals (nickel, gold, silver) causes the element to look better,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to the potential of accurate forming and customization to custom solutions, magnetic components can be produced in a variety of geometric configurations, which makes them more universal,
- Key role in modern industrial fields – they are commonly used in computer drives, electromotive mechanisms, advanced medical instruments, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices
Disadvantages
- To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Limited possibility of making nuts in the magnet and complicated forms - recommended is cover - magnetic holder.
- Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which becomes key in the context of child safety. Furthermore, tiny parts of these devices can be problematic in diagnostics medical after entering the body.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what it depends on?
- with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
- whose thickness is min. 10 mm
- with an ground touching surface
- with total lack of distance (without paint)
- under axial force direction (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Distance – the presence of foreign body (rust, tape, gap) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
- Direction of force – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Material composition – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Surface finish – ideal contact is obtained only on polished steel. Any scratches and bumps create air cushions, reducing force.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet’s surface and the plate reduces the load capacity.
Warnings
Flammability
Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
Respect the power
Handle with care. Neodymium magnets attract from a distance and connect with massive power, often faster than you can move away.
Crushing risk
Big blocks can smash fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.
Risk of cracking
Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Compass and GPS
An intense magnetic field disrupts the functioning of compasses in smartphones and navigation systems. Keep magnets near a smartphone to prevent damaging the sensors.
Warning for allergy sufferers
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If skin irritation appears, cease handling magnets and use protective gear.
Adults only
Adult use only. Tiny parts pose a choking risk, leading to intestinal necrosis. Store away from kids and pets.
Do not overheat magnets
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and strength.
Health Danger
For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or request help to handle the magnets.
Protect data
Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, hearing aids, timepieces).
