Advantages and disadvantages of neodymium magnets.
Benefits
- Their power remains stable, and after approximately 10 years it decreases only by ~1% (theoretically),
- Magnets effectively protect themselves against loss of magnetization caused by external fields,
- By covering with a shiny coating of nickel, the element has an elegant look,
- They are known for high magnetic induction at the operating surface, making them more effective,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
- Thanks to modularity in shaping and the ability to customize to individual projects,
- Fundamental importance in electronics industry – they find application in mass storage devices, brushless drives, advanced medical instruments, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in compact constructions
Disadvantages
- They are prone to damage upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
- 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 when using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Limited possibility of making threads in the magnet and complex forms - recommended is a housing - mounting mechanism.
- Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Breakaway strength of the magnet in ideal conditions – what it depends on?
- on a block made of mild steel, perfectly concentrating the magnetic flux
- whose transverse dimension reaches at least 10 mm
- with a surface free of scratches
- with zero gap (no coatings)
- for force applied at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Space between surfaces – every millimeter of distance (caused e.g. by veneer or dirt) diminishes the pulling force, often by half at just 0.5 mm.
- Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
- Element thickness – to utilize 100% power, the steel must be adequately massive. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
- Steel grade – the best choice is high-permeability steel. Stainless steels may attract less.
- Surface quality – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
- Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate lowers the holding force.
Precautions when working with NdFeB magnets
Magnetic media
Powerful magnetic fields can destroy records on credit cards, hard drives, and other magnetic media. Stay away of at least 10 cm.
Handling guide
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Think ahead.
Warning for allergy sufferers
A percentage of the population suffer from a contact allergy to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact may cause dermatitis. We recommend use protective gloves.
Pacemakers
Health Alert: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Keep away from electronics
A strong magnetic field negatively affects the operation of magnetometers in smartphones and GPS navigation. Do not bring magnets near a smartphone to avoid damaging the sensors.
Power loss in heat
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. This process is irreversible.
Physical harm
Protect your hands. Two large magnets will snap together immediately with a force of several hundred kilograms, crushing everything in their path. Be careful!
Mechanical processing
Combustion risk: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Danger to the youngest
Neodymium magnets are not intended for children. Swallowing several magnets can lead to them connecting inside the digestive tract, which poses a direct threat to life and necessitates urgent medical intervention.
Eye protection
Despite metallic appearance, neodymium is brittle and not impact-resistant. Do not hit, as the magnet may crumble into hazardous fragments.
