Strengths as well as weaknesses of neodymium magnets.
Pros
- Their strength is durable, and after approximately ten years it drops only by ~1% (according to research),
- Neodymium magnets remain exceptionally resistant to magnetic field loss caused by external interference,
- By using a shiny coating of silver, the element gains an aesthetic look,
- They feature high magnetic induction at the operating surface, which improves attraction properties,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to versatility in shaping and the capacity to modify to specific needs,
- Universal use in high-tech industry – they are commonly used in computer drives, drive modules, medical devices, as well as multitasking production systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage and increases the magnet's durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
- Due to limitations in producing threads and complicated forms in magnets, we recommend using casing - magnetic holder.
- Health risk resulting from small fragments of magnets are risky, in case of ingestion, which is particularly important in the context of child health protection. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a block made of mild steel, effectively closing the magnetic flux
- whose transverse dimension equals approx. 10 mm
- characterized by lack of roughness
- under conditions of ideal adhesion (surface-to-surface)
- during pulling in a direction vertical to the mounting surface
- in stable room temperature
Determinants of practical lifting force of a magnet
- Clearance – existence of any layer (paint, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Chemical composition of the base – mild steel attracts best. Higher carbon content reduce magnetic permeability and lifting capacity.
- Surface finish – ideal contact is possible only on polished steel. Rough texture 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 measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, however under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate decreases the holding force.
Safety rules for work with NdFeB magnets
Material brittleness
Watch out for shards. Magnets can explode upon uncontrolled impact, launching sharp fragments into the air. Eye protection is mandatory.
Warning for heart patients
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have medical devices.
Product not for children
These products are not intended for children. Swallowing a few magnets can lead to them pinching intestinal walls, which constitutes a direct threat to life and necessitates urgent medical intervention.
Serious injuries
Big blocks can crush fingers in a fraction of a second. Never put your hand between two strong magnets.
Electronic devices
Data protection: Strong magnets can ruin payment cards and delicate electronics (pacemakers, medical aids, mechanical watches).
Conscious usage
Handle with care. Rare earth magnets attract from a long distance and connect with massive power, often faster than you can react.
Nickel coating and allergies
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease working with magnets and use protective gear.
Impact on smartphones
Navigation devices and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the sensors in your phone.
Power loss in heat
Keep cool. Neodymium magnets are sensitive to temperature. If you need operation above 80°C, inquire about HT versions (H, SH, UH).
Mechanical processing
Drilling and cutting of neodymium magnets carries a risk of fire risk. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
