Strengths as well as weaknesses of neodymium magnets.
Advantages
- Their power remains stable, and after approximately ten years it decreases only by ~1% (according to research),
- They are noted for resistance to demagnetization induced by external field influence,
- In other words, due to the metallic surface of gold, the element gains visual value,
- The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Possibility of individual machining as well as adjusting to individual conditions,
- Universal use in advanced technology sectors – they find application in HDD drives, electric drive systems, precision medical tools, also multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which enables their usage in small systems
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power 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
- They rust in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complex shapes in magnets, we recommend using casing - magnetic holder.
- Health risk resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
- With large orders the cost of neodymium magnets can be a barrier,
Lifting parameters
Optimal lifting capacity of a neodymium magnet – what it depends on?
- on a block made of structural steel, optimally conducting the magnetic flux
- with a thickness no less than 10 mm
- with an ideally smooth touching surface
- with zero gap (without paint)
- under vertical application of breakaway force (90-degree angle)
- in neutral thermal conditions
Practical lifting capacity: influencing factors
- Space between magnet and steel – every millimeter of distance (caused e.g. by veneer or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Steel grade – the best choice is high-permeability steel. Cast iron may generate lower lifting capacity.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Heat warning
Watch the temperature. Exposing the magnet to high heat will destroy its properties and pulling force.
Pacemakers
For implant holders: Powerful magnets disrupt medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.
Electronic hazard
Very strong magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
No play value
Always store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets connecting inside the body are fatal.
Avoid contact if allergic
Certain individuals experience a hypersensitivity to Ni, which is the common plating for neodymium magnets. Frequent touching can result in dermatitis. We recommend wear safety gloves.
Machining danger
Fire hazard: Rare earth powder is explosive. Avoid machining magnets without safety gear as this risks ignition.
Handling rules
Handle magnets with awareness. Their huge power can shock even experienced users. Stay alert and respect their force.
Pinching danger
Mind your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Risk of cracking
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets leads to them breaking into small pieces.
GPS Danger
Be aware: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your mobile, device, and GPS.
