Advantages as well as disadvantages of neodymium magnets.
Strengths
- They virtually do not lose power, because even after 10 years the decline in efficiency is only ~1% (according to literature),
- They possess excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
- By covering with a reflective coating of gold, the element gains an aesthetic look,
- Magnetic induction on the surface of the magnet turns out to be strong,
- Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to versatility in forming and the ability to customize to complex applications,
- Fundamental importance in innovative solutions – they are commonly used in hard drives, electromotive mechanisms, precision medical tools, and modern systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Cons
- They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in a protective case. Such protection not only protects the magnet but also improves its resistance to damage
- We warn that neodymium magnets can reduce 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 rust. Therefore when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We recommend a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated shapes.
- Potential hazard resulting from small fragments of magnets are risky, if swallowed, which gains importance in the context of child safety. Additionally, tiny parts of these devices can be problematic in diagnostics medical when they are in the body.
- Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications
Pull force analysis
Maximum holding power of the magnet – what affects it?
- with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
- whose thickness equals approx. 10 mm
- characterized by smoothness
- under conditions of no distance (metal-to-metal)
- during pulling in a direction perpendicular to the plane
- at conditions approx. 20°C
What influences lifting capacity in practice
- Gap between magnet and steel – every millimeter of distance (caused e.g. by varnish or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
- Force direction – catalog parameter refers to detachment vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of generating force.
- Material type – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
- Smoothness – ideal contact is obtained only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal environment – heating the magnet causes a temporary drop of force. It is worth remembering the thermal limit for a given model.
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the load capacity.
Protect data
Do not bring magnets near a purse, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Finger safety
Danger of trauma: The pulling power is so immense that it can cause blood blisters, crushing, and broken bones. Use thick gloves.
Impact on smartphones
Remember: neodymium magnets generate a field that interferes with precision electronics. Keep a separation from your phone, device, and GPS.
Nickel coating and allergies
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If skin irritation happens, cease handling magnets and use protective gear.
Danger to pacemakers
For implant holders: Powerful magnets affect electronics. Maintain minimum 30 cm distance or request help to handle the magnets.
Respect the power
Before starting, read the rules. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Machining danger
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Beware of splinters
NdFeB magnets are sintered ceramics, meaning they are prone to chipping. Impact of two magnets will cause them breaking into shards.
Do not overheat magnets
Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. The loss of strength is permanent.
Keep away from children
Adult use only. Tiny parts pose a choking risk, leading to severe trauma. Keep out of reach of kids and pets.
