Strengths as well as weaknesses of rare earth magnets.
Advantages
- They do not lose strength, even over nearly ten years – the drop in power is only ~1% (according to tests),
- They possess excellent resistance to magnetic field loss as a result of external magnetic sources,
- By using a lustrous layer of silver, the element gains an modern look,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- 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 complex needs,
- Huge importance in electronics industry – they serve a role in data components, electric motors, diagnostic systems, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 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 producing threads and complicated forms in magnets, we recommend using a housing - magnetic mount.
- Health risk related to microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these devices can disrupt the diagnostic process medical in case of swallowing.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what it depends on?
- on a plate made of structural steel, effectively closing the magnetic field
- with a cross-section minimum 10 mm
- with a surface cleaned and smooth
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (in the magnet axis)
- at conditions approx. 20°C
Key elements affecting lifting force
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) significantly weakens 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 drastically, often to levels of 20-30% of the maximum value.
- Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is pure iron steel. Stainless steels may attract less.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they lose power, and at low temperatures they can be stronger (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate lowers the load capacity.
H&S for magnets
Handling guide
Handle magnets with awareness. Their powerful strength can surprise even experienced users. Stay alert and respect their power.
Heat sensitivity
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and pulling force.
ICD Warning
Individuals with a ICD have to maintain an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.
Avoid contact if allergic
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, prevent touching magnets with bare hands or opt for coated magnets.
Fire warning
Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this risks ignition.
Magnet fragility
Beware of splinters. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Precision electronics
A strong magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Maintain magnets near a smartphone to avoid breaking the sensors.
Swallowing risk
NdFeB magnets are not intended for children. Accidental ingestion of a few magnets can lead to them pinching intestinal walls, which poses a critical condition and necessitates urgent medical intervention.
Hand protection
Big blocks can crush fingers instantly. Do not put your hand between two strong magnets.
Cards and drives
Device Safety: Neodymium magnets can ruin payment cards and delicate electronics (heart implants, medical aids, timepieces).
