Strengths as well as weaknesses of neodymium magnets.
Advantages
- Their power is durable, and after around 10 years it decreases only by ~1% (according to research),
- They feature excellent resistance to magnetic field loss as a result of external magnetic sources,
- A magnet with a shiny gold surface has an effective appearance,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and are able to act (depending on the shape) even at a temperature of 230°C or more...
- Due to the option of precise shaping and adaptation to individualized solutions, neodymium magnets can be created in a broad palette of forms and dimensions, which expands the range of possible applications,
- Wide application in modern industrial fields – they are commonly used in magnetic memories, drive modules, precision medical tools, also industrial machines.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Weaknesses
- They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in a protective case. Such protection not only protects the magnet but also increases its resistance to damage
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Limited ability of making nuts in the magnet and complex forms - recommended is cover - mounting mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which becomes key in the context of child health protection. It is also worth noting that tiny parts of these products can disrupt the diagnostic process medical after entering the body.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Maximum magnetic pulling force – what it depends on?
- using a plate made of mild steel, functioning as a ideal flux conductor
- with a thickness minimum 10 mm
- with a surface cleaned and smooth
- under conditions of gap-free contact (surface-to-surface)
- under vertical force vector (90-degree angle)
- at ambient temperature approx. 20 degrees Celsius
Determinants of lifting force in real conditions
- Distance – existence of any layer (rust, tape, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Load vector – highest force is available only during pulling at a 90° angle. The shear force of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Steel grade – the best choice is high-permeability steel. Hardened steels may attract less.
- Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Unevenness creates an air distance.
- Thermal factor – high temperature reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined with the use of a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate lowers the lifting capacity.
Safety rules for work with neodymium magnets
Permanent damage
Standard neodymium magnets (N-type) lose power when the temperature goes above 80°C. This process is irreversible.
Pacemakers
Health Alert: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Immense force
Handle with care. Rare earth magnets act from a long distance and connect with massive power, often faster than you can react.
Magnet fragility
Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Impact of two magnets leads to them cracking into shards.
Precision electronics
A powerful magnetic field interferes with the functioning of magnetometers in phones and navigation systems. Maintain magnets close to a smartphone to avoid damaging the sensors.
Threat to electronics
Avoid bringing magnets close to a purse, laptop, or TV. The magnetic field can destroy these devices and wipe information from cards.
Allergy Warning
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation appears, immediately stop handling magnets and wear gloves.
Dust explosion hazard
Dust produced during cutting of magnets is flammable. Do not drill into magnets unless you are an expert.
Serious injuries
Mind your fingers. Two large magnets will join instantly with a force of massive weight, crushing anything in their path. Be careful!
Swallowing risk
Only for adults. Tiny parts pose a choking risk, leading to intestinal necrosis. Keep out of reach of kids and pets.
