Pros and cons of neodymium magnets.
Benefits
- They do not lose strength, even after around ten years – the drop in strength is only ~1% (according to tests),
- Neodymium magnets prove to be highly resistant to demagnetization caused by external interference,
- Thanks to the shiny finish, the coating of Ni-Cu-Ni, gold, or silver gives an aesthetic appearance,
- The surface of neodymium magnets generates a maximum magnetic field – this is a key feature,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to freedom in designing and the capacity to modify to complex applications,
- Huge importance in future technologies – they serve a role in hard drives, electric motors, advanced medical instruments, and modern systems.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Limitations
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We recommend keeping them in a strong case, which not only secures them against impacts but also raises their durability
- Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic holder, due to difficulties in producing threads inside the magnet and complex forms.
- Potential hazard to health – tiny shards of magnets can be dangerous, if swallowed, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these devices can disrupt the diagnostic process medical in case of swallowing.
- Due to complex production process, their price is relatively high,
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the use of a sheet made of special test steel, guaranteeing maximum field concentration
- possessing a thickness of at least 10 mm to avoid saturation
- characterized by smoothness
- under conditions of gap-free contact (metal-to-metal)
- during pulling in a direction perpendicular to the mounting surface
- in temp. approx. 20°C
Lifting capacity in real conditions – factors
- Clearance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, which lowers power rapidly (even by 50% at 0.5 mm).
- Direction of force – highest force is available only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of converting into lifting capacity.
- Chemical composition of the base – low-carbon steel gives the best results. Alloy steels decrease magnetic permeability and lifting capacity.
- Surface finish – full contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, weakening the magnet.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity was determined with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.
Precautions when working with NdFeB magnets
Impact on smartphones
Be aware: neodymium magnets produce a field that interferes with sensitive sensors. Keep a separation from your phone, device, and GPS.
Do not drill into magnets
Combustion risk: Neodymium dust is explosive. Avoid machining magnets without safety gear as this may cause fire.
Safe distance
Avoid bringing magnets near a wallet, laptop, or screen. The magnetic field can permanently damage these devices and erase data from cards.
Warning for allergy sufferers
Medical facts indicate that the nickel plating (the usual finish) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands and opt for coated magnets.
Do not overheat magnets
Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. This process is irreversible.
Magnet fragility
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
No play value
Absolutely store magnets out of reach of children. Choking hazard is significant, and the consequences of magnets clamping inside the body are tragic.
Danger to pacemakers
Warning for patients: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Conscious usage
Handle with care. Neodymium magnets attract from a distance and connect with huge force, often faster than you can react.
Bone fractures
Protect your hands. Two large magnets will snap together instantly with a force of massive weight, destroying everything in their path. Be careful!
