Advantages as well as disadvantages of neodymium magnets.
Advantages
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
- They have excellent resistance to magnetism drop due to external fields,
- In other words, due to the smooth finish of silver, the element gains a professional look,
- Magnets exhibit extremely high magnetic induction on the surface,
- Through (appropriate) combination of ingredients, they can achieve high thermal resistance, allowing for functioning at temperatures approaching 230°C and above...
- Possibility of detailed modeling and modifying to concrete applications,
- Fundamental importance in modern technologies – they are commonly used in magnetic memories, brushless drives, diagnostic systems, also technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- We recommend cover - magnetic mount, due to difficulties in producing threads inside the magnet and complicated shapes.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the aspect of protecting the youngest. Furthermore, small components of these magnets can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Detachment force of the magnet in optimal conditions – what contributes to it?
- using a base made of low-carbon steel, functioning as a ideal flux conductor
- possessing a thickness of at least 10 mm to avoid saturation
- with a plane perfectly flat
- with direct contact (no coatings)
- during pulling in a direction vertical to the mounting surface
- in temp. approx. 20°C
Key elements affecting lifting force
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Base massiveness – insufficiently thick plate does not close the flux, causing part of the power to be lost into the air.
- Chemical composition of the base – low-carbon steel attracts best. Alloy admixtures decrease magnetic permeability and holding force.
- Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was carried out on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under shearing force the lifting capacity is smaller. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Handling guide
Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.
Bodily injuries
Big blocks can crush fingers instantly. Never place your hand betwixt two strong magnets.
Permanent damage
Monitor thermal conditions. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and strength.
Adults only
Always store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets clamping inside the body are life-threatening.
Fire warning
Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Magnets are brittle
Neodymium magnets are ceramic materials, which means they are very brittle. Impact of two magnets leads to them shattering into small pieces.
Keep away from computers
Data protection: Strong magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Skin irritation risks
Medical facts indicate that nickel (standard magnet coating) is a common allergen. If you have an allergy, avoid touching magnets with bare hands and choose encased magnets.
Life threat
For implant holders: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or request help to handle the magnets.
Magnetic interference
Navigation devices and smartphones are extremely sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
