Advantages and disadvantages of rare earth magnets.
Advantages
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (according to literature),
- They do not lose their magnetic properties even under close interference source,
- In other words, due to the aesthetic layer of nickel, the element becomes visually attractive,
- They show high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of exact creating as well as modifying to specific needs,
- Significant place in modern industrial fields – they are commonly used in hard drives, electromotive mechanisms, diagnostic systems, as well as modern systems.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in small systems
Limitations
- To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution protects the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of making threads in the magnet and complicated shapes - preferred is cover - magnet mounting.
- Potential hazard to health – tiny shards of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Furthermore, small elements of these products can disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is economically unviable,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- on a plate made of structural steel, effectively closing the magnetic field
- possessing a thickness of minimum 10 mm to avoid saturation
- with an ideally smooth contact surface
- under conditions of gap-free contact (surface-to-surface)
- under perpendicular force direction (90-degree angle)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Gap between surfaces – even a fraction of a millimeter of separation (caused e.g. by veneer or unevenness) significantly weakens the pulling force, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Substrate thickness – to utilize 100% power, the steel must be sufficiently thick. Paper-thin metal limits the attraction force (the magnet "punches through" it).
- Steel grade – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal weaken the grip.
- Temperature – temperature increase results in weakening of force. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. In addition, even a minimal clearance between the magnet and the plate lowers the lifting capacity.
Warnings
Eye protection
Protect your eyes. Magnets can explode upon violent connection, ejecting shards into the air. Eye protection is mandatory.
Thermal limits
Keep cool. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).
Dust is flammable
Fire warning: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Precision electronics
Navigation devices and smartphones are extremely sensitive to magnetism. Close proximity with a strong magnet can ruin the internal compass in your phone.
Threat to electronics
Intense magnetic fields can erase data on credit cards, HDDs, and storage devices. Keep a distance of at least 10 cm.
Allergic reactions
It is widely known that nickel (standard magnet coating) is a common allergen. If your skin reacts to metals, avoid touching magnets with bare hands or select coated magnets.
Do not underestimate power
Exercise caution. Neodymium magnets attract from a long distance and snap with huge force, often quicker than you can react.
Bodily injuries
Risk of injury: The attraction force is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Swallowing risk
Always store magnets away from children. Risk of swallowing is high, and the effects of magnets clamping inside the body are tragic.
Implant safety
Patients with a pacemaker must maintain an safe separation from magnets. The magnetic field can interfere with the operation of the implant.
