Advantages as well as disadvantages of neodymium magnets.
Benefits
- Their power is durable, and after approximately 10 years it drops only by ~1% (according to research),
- Neodymium magnets are highly resistant to demagnetization caused by magnetic disturbances,
- Thanks to the shiny finish, the surface of nickel, gold, or silver gives an professional appearance,
- Magnetic induction on the top side of the magnet remains exceptional,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to modularity in designing and the ability to modify to individual projects,
- Key role in modern technologies – they are used in computer drives, electric motors, medical devices, also multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- At very strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing threads and complex shapes in magnets, we recommend using casing - magnetic mechanism.
- Potential hazard resulting from small fragments of magnets pose a threat, if swallowed, which is particularly important in the context of child safety. Furthermore, small components of these products can disrupt the diagnostic process medical after entering the body.
- Due to neodymium price, their price exceeds standard values,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what affects it?
- with the use of a yoke made of special test steel, guaranteeing maximum field concentration
- possessing a massiveness of at least 10 mm to ensure full flux closure
- characterized by smoothness
- under conditions of gap-free contact (surface-to-surface)
- under perpendicular application of breakaway force (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Distance – existence of foreign body (rust, dirt, gap) acts as an insulator, which reduces power rapidly (even by 50% at 0.5 mm).
- Direction of force – maximum parameter is available only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel type – low-carbon steel attracts best. Alloy admixtures reduce magnetic permeability and lifting capacity.
- Surface condition – ground elements ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under shearing force the holding force is lower. Moreover, even a slight gap between the magnet and the plate decreases the holding force.
H&S for magnets
Sensitization to coating
It is widely known that nickel (the usual finish) is a potent allergen. For allergy sufferers, prevent direct skin contact and select coated magnets.
Keep away from computers
Avoid bringing magnets near a purse, computer, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Serious injuries
Risk of injury: The attraction force is so immense that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.
ICD Warning
People with a ICD must keep an absolute distance from magnets. The magnetism can interfere with the operation of the implant.
Dust is flammable
Powder produced during machining of magnets is flammable. Do not drill into magnets unless you are an expert.
Danger to the youngest
These products are not intended for children. Swallowing multiple magnets may result in them pinching intestinal walls, which constitutes a direct threat to life and necessitates urgent medical intervention.
Compass and GPS
A strong magnetic field interferes with the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to avoid breaking the sensors.
Demagnetization risk
Standard neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. Damage is permanent.
Fragile material
Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets leads to them breaking into small pieces.
Handling rules
Use magnets consciously. Their immense force can surprise even professionals. Be vigilant and do not underestimate their power.
