Pros and cons of neodymium magnets.
Strengths
- Their power is durable, and after around ten years it decreases only by ~1% (according to research),
- They maintain their magnetic properties even under external field action,
- The use of an aesthetic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Considering the potential of precise shaping and adaptation to specialized requirements, magnetic components can be created in a broad palette of forms and dimensions, which increases their versatility,
- Wide application in future technologies – they are utilized in data components, brushless drives, advanced medical instruments, also technologically advanced constructions.
- Thanks to their power density, small magnets offer high operating force, with minimal size,
Weaknesses
- They are prone to damage 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 reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in creating nuts and complicated shapes in magnets, we propose using casing - magnetic mechanism.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these magnets can be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities
Holding force characteristics
Magnetic strength at its maximum – what contributes to it?
- with the application of a yoke made of low-carbon steel, ensuring maximum field concentration
- whose transverse dimension is min. 10 mm
- with an polished contact surface
- without any clearance between the magnet and steel
- during detachment in a direction perpendicular to the mounting surface
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by veneer or dirt) significantly weakens the pulling force, often by half at just 0.5 mm.
- Force direction – note that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be adequately massive. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is pure iron steel. Cast iron may generate lower lifting capacity.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they are weaker, and in frost gain strength (up to a certain limit).
Holding force was tested on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Safe handling of neodymium magnets
Threat to navigation
A strong magnetic field negatively affects the functioning of magnetometers in phones and navigation systems. Maintain magnets near a smartphone to avoid breaking the sensors.
Electronic hazard
Avoid bringing magnets near a purse, computer, or screen. The magnetism can destroy these devices and wipe information from cards.
Sensitization to coating
Certain individuals experience a hypersensitivity to Ni, which is the common plating for neodymium magnets. Extended handling might lead to dermatitis. We strongly advise wear protective gloves.
Life threat
Health Alert: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Product not for children
Only for adults. Tiny parts can be swallowed, causing severe trauma. Store away from children and animals.
Fire warning
Powder created during grinding of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
Maximum temperature
Regular neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.
Beware of splinters
NdFeB magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets will cause them shattering into shards.
Physical harm
Watch your fingers. Two powerful magnets will snap together instantly with a force of massive weight, crushing anything in their path. Be careful!
Do not underestimate power
Before starting, check safety instructions. Sudden snapping can break the magnet or hurt your hand. Think ahead.
