Strengths and weaknesses of rare earth magnets.
Advantages
- They have unchanged lifting capacity, and over nearly 10 years their attraction force decreases symbolically – ~1% (in testing),
- Neodymium magnets are remarkably resistant to loss of magnetic properties caused by magnetic disturbances,
- In other words, due to the reflective finish of nickel, the element becomes visually attractive,
- Magnets are characterized by excellent magnetic induction on the surface,
- Through (appropriate) combination of ingredients, they can achieve high thermal strength, enabling operation at temperatures reaching 230°C and above...
- Thanks to flexibility in designing and the ability to modify to specific needs,
- Versatile presence in electronics industry – they find application in magnetic memories, drive modules, precision medical tools, and technologically advanced constructions.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in power. 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Due to limitations in producing threads and complicated shapes in magnets, we recommend using cover - magnetic holder.
- Potential hazard resulting from small fragments of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child health protection. Additionally, small components of these magnets are able to disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum holding power of the magnet – what it depends on?
- on a plate made of structural steel, effectively closing the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- with an polished contact surface
- with total lack of distance (no coatings)
- during pulling in a direction perpendicular to the plane
- at temperature room level
Key elements affecting lifting force
- Distance – the presence of any layer (rust, tape, gap) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is reached only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Metal type – different alloys reacts the same. High carbon content weaken the attraction effect.
- Smoothness – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Thermal environment – heating the magnet results in weakening of force. Check the thermal limit for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Skin irritation risks
It is widely known that nickel (the usual finish) is a common allergen. If you have an allergy, avoid direct skin contact or choose coated magnets.
Handling guide
Exercise caution. Rare earth magnets attract from a distance and snap with huge force, often quicker than you can react.
Keep away from electronics
GPS units and smartphones are highly susceptible to magnetic fields. Close proximity with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Thermal limits
Do not overheat. Neodymium magnets are susceptible to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Dust explosion hazard
Fire warning: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Shattering risk
Watch out for shards. Magnets can fracture upon uncontrolled impact, launching shards into the air. Wear goggles.
Finger safety
Large magnets can smash fingers in a fraction of a second. Never place your hand between two attracting surfaces.
Electronic hazard
Very strong magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Keep a distance of at least 10 cm.
Warning for heart patients
Patients with a heart stimulator should keep an large gap from magnets. The magnetism can stop the operation of the implant.
No play value
Neodymium magnets are not intended for children. Eating a few magnets can lead to them pinching intestinal walls, which poses a direct threat to life and requires urgent medical intervention.
