Pros as well as cons of neodymium magnets.
Strengths
- Their strength remains stable, and after around 10 years it drops only by ~1% (theoretically),
- They are noted for resistance to demagnetization induced by external disturbances,
- A magnet with a metallic gold surface is more attractive,
- The surface of neodymium magnets generates a concentrated magnetic field – this is one of their assets,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to freedom in designing and the capacity to modify to unusual requirements,
- Key role in future technologies – they are used in mass storage devices, brushless drives, diagnostic systems, and multitasking production systems.
- Compactness – despite small sizes they generate large force, making them ideal for precision applications
Cons
- 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 improves its resistance to damage
- Neodymium magnets decrease their power 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- We recommend casing - magnetic mechanism, due to difficulties in creating nuts inside the magnet and complicated shapes.
- Possible danger to health – tiny shards of magnets are risky, when accidentally swallowed, which gains importance in the context of child health protection. Furthermore, small components of these devices can be problematic in diagnostics medical when they are in the body.
- Due to neodymium price, their price is relatively high,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- with the application of a yoke made of low-carbon steel, guaranteeing maximum field concentration
- whose transverse dimension reaches at least 10 mm
- with a surface cleaned and smooth
- with direct contact (without paint)
- during detachment in a direction perpendicular to the plane
- in neutral thermal conditions
Magnet lifting force in use – key factors
- Space between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
- Direction of force – highest force is obtained only during perpendicular pulling. The resistance to sliding of the magnet along the surface is usually many times lower (approx. 1/5 of the lifting capacity).
- Base massiveness – insufficiently thick steel does not close the flux, causing part of the power to be wasted to the other side.
- Material composition – different alloys reacts the same. High carbon content worsen the attraction effect.
- Smoothness – full contact is obtained only on polished steel. Rough texture create air cushions, reducing force.
- Temperature – temperature increase results in weakening of force. Check the thermal limit for a given model.
Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under shearing force the lifting capacity is smaller. Additionally, even a slight gap between the magnet and the plate lowers the lifting capacity.
Precautions when working with neodymium magnets
Adults only
NdFeB magnets are not suitable for play. Swallowing several magnets may result in them connecting inside the digestive tract, which constitutes a direct threat to life and requires immediate surgery.
Handling rules
Be careful. Neodymium magnets act from a distance and connect with massive power, often quicker than you can react.
ICD Warning
Individuals with a heart stimulator have to maintain an safe separation from magnets. The magnetism can interfere with the operation of the implant.
Hand protection
Risk of injury: The pulling power is so great that it can cause hematomas, pinching, and even bone fractures. Protective gloves are recommended.
Thermal limits
Keep cool. Neodymium magnets are susceptible to temperature. If you require resistance above 80°C, inquire about special high-temperature series (H, SH, UH).
Combustion hazard
Dust created during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Warning for allergy sufferers
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, immediately stop working with magnets and use protective gear.
Material brittleness
Watch out for shards. Magnets can fracture upon violent connection, launching sharp fragments into the air. Wear goggles.
Magnetic media
Avoid bringing magnets close to a purse, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
Phone sensors
Navigation devices and smartphones are highly susceptible to magnetic fields. Close proximity with a strong magnet can ruin the internal compass in your phone.
