Strengths as well as weaknesses of neodymium magnets.
Strengths
- They retain magnetic properties for almost ten years – the loss is just ~1% (according to analyses),
- They are noted for resistance to demagnetization induced by external disturbances,
- Thanks to the elegant finish, the layer of Ni-Cu-Ni, gold, or silver-plated gives an professional appearance,
- Magnets have extremely high magnetic induction on the outer layer,
- Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the form) even at a temperature of 230°C or more...
- Due to the potential of precise forming and adaptation to custom requirements, NdFeB magnets can be produced in a wide range of forms and dimensions, which makes them more universal,
- Key role in future technologies – they are utilized in mass storage devices, brushless drives, medical devices, as well as industrial machines.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Limitations
- 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
- 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 durability even at temperatures 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 stable to moisture, when using outdoors
- Limited ability of producing nuts in the magnet and complicated shapes - preferred is casing - magnet mounting.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Additionally, small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
- Due to expensive raw materials, their price exceeds standard values,
Holding force characteristics
Detachment force of the magnet in optimal conditions – what it depends on?
- with the contact of a yoke made of special test steel, guaranteeing full magnetic saturation
- with a cross-section no less than 10 mm
- with a plane perfectly flat
- with total lack of distance (without impurities)
- for force applied at a right angle (pull-off, not shear)
- at ambient temperature room level
Lifting capacity in practice – influencing factors
- Distance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Force direction – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of maximum force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel type – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
- Thermal environment – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Protective goggles
Protect your eyes. Magnets can fracture upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.
Do not drill into magnets
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this risks ignition.
Electronic devices
Do not bring magnets close to a purse, laptop, or screen. The magnetism can destroy these devices and erase data from cards.
GPS and phone interference
Note: neodymium magnets produce a field that disrupts precision electronics. Keep a safe distance from your phone, tablet, and GPS.
Power loss in heat
Do not overheat. NdFeB magnets are susceptible to heat. If you need resistance above 80°C, look for HT versions (H, SH, UH).
Avoid contact if allergic
Medical facts indicate that nickel (the usual finish) is a potent allergen. If your skin reacts to metals, prevent touching magnets with bare hands and select encased magnets.
Respect the power
Handle magnets consciously. Their immense force can shock even experienced users. Stay alert and respect their power.
Do not give to children
Always store magnets out of reach of children. Choking hazard is high, and the consequences of magnets clamping inside the body are very dangerous.
Implant safety
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Crushing force
Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!
