Advantages and disadvantages of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- They show high resistance to demagnetization induced by presence of other magnetic fields,
- By using a reflective coating of nickel, the element gains an elegant look,
- The surface of neodymium magnets generates a strong magnetic field – this is a distinguishing feature,
- Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for operation at temperatures approaching 230°C and above...
- Thanks to modularity in designing and the ability to customize to unusual requirements,
- Fundamental importance in modern industrial fields – they find application in data components, motor assemblies, medical equipment, and industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Weaknesses
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
- Neodymium magnets lose power when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- They rust in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited ability of making threads in the magnet and complicated shapes - recommended is a housing - mounting mechanism.
- Health risk related to microscopic parts of magnets are risky, if swallowed, which becomes key in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Holding force characteristics
Maximum lifting force for a neodymium magnet – what it depends on?
- using a plate made of mild steel, functioning as a ideal flux conductor
- whose thickness is min. 10 mm
- with a plane perfectly flat
- without the slightest clearance between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at temperature room level
Impact of factors on magnetic holding capacity in practice
- Gap (betwixt the magnet and the plate), because even a microscopic clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet exhibits much less (typically approx. 20-30% of nominal force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of converting into lifting capacity.
- Material type – the best choice is high-permeability steel. Stainless steels may generate lower lifting capacity.
- Surface quality – the more even the surface, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
- Temperature influence – hot environment weakens pulling force. Too high temperature can permanently demagnetize the magnet.
Lifting capacity was measured by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under shearing force the holding force is lower. Additionally, even a minimal clearance between the magnet and the plate reduces the lifting capacity.
H&S for magnets
Safe distance
Avoid bringing magnets near a purse, laptop, or screen. The magnetic field can permanently damage these devices and wipe information from cards.
Caution required
Handle with care. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can move away.
GPS and phone interference
Be aware: rare earth magnets produce a field that disrupts precision electronics. Maintain a separation from your phone, tablet, and GPS.
Shattering risk
Despite metallic appearance, the material is brittle and not impact-resistant. Avoid impacts, as the magnet may crumble into hazardous fragments.
Heat sensitivity
Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Bodily injuries
Big blocks can crush fingers in a fraction of a second. Never place your hand between two attracting surfaces.
Do not drill into magnets
Combustion risk: Neodymium dust is explosive. Avoid machining magnets in home conditions as this risks ignition.
Skin irritation risks
It is widely known that nickel (the usual finish) is a common allergen. For allergy sufferers, prevent direct skin contact or choose versions in plastic housing.
Medical interference
People with a ICD must keep an safe separation from magnets. The magnetism can interfere with the functioning of the implant.
Product not for children
Adult use only. Small elements pose a choking risk, leading to intestinal necrosis. Store out of reach of children and animals.
