Advantages and disadvantages of neodymium magnets.
Advantages
- They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
- They have excellent resistance to weakening of magnetic properties as a result of opposing magnetic fields,
- Thanks to the reflective finish, the coating of Ni-Cu-Ni, gold, or silver gives an elegant appearance,
- Magnets exhibit impressive magnetic induction on the outer layer,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Due to the possibility of accurate forming and customization to individualized needs, magnetic components can be created in a broad palette of shapes and sizes, which amplifies use scope,
- Versatile presence in electronics industry – they are used in hard drives, electric drive systems, precision medical tools, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which enables their usage in compact constructions
Disadvantages
- They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- 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 corrode. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of producing threads in the magnet and complex shapes - recommended is a housing - mounting mechanism.
- Possible danger related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these magnets can be problematic in diagnostics medical when they are in the body.
- With large orders the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- with the application of a sheet made of special test steel, guaranteeing maximum field concentration
- with a cross-section no less than 10 mm
- with an polished touching surface
- under conditions of gap-free contact (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- at ambient temperature room level
Determinants of practical lifting force of a magnet
- Air gap (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) can cause a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the maximum value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Material type – the best choice is pure iron steel. Hardened steels may attract less.
- Surface condition – ground elements ensure maximum contact, which increases field saturation. Uneven metal weaken the grip.
- Thermal factor – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity was measured using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the load capacity is reduced by as much as 75%. Additionally, even a slight gap between the magnet and the plate lowers the holding force.
H&S for magnets
Immense force
Use magnets consciously. Their huge power can shock even experienced users. Plan your moves and do not underestimate their power.
Protect data
Very strong magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
Magnet fragility
Beware of splinters. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Heat warning
Do not overheat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Fire risk
Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this may cause fire.
Sensitization to coating
Studies show that the nickel plating (the usual finish) is a common allergen. If you have an allergy, avoid touching magnets with bare hands and select coated magnets.
Do not give to children
Always store magnets away from children. Ingestion danger is high, and the effects of magnets connecting inside the body are life-threatening.
Medical implants
Medical warning: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have medical devices.
Keep away from electronics
A powerful magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent damaging the sensors.
Bodily injuries
Large magnets can smash fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.
