Advantages as well as disadvantages of rare earth magnets.
Advantages
- Their magnetic field is durable, and after around 10 years it drops only by ~1% (theoretically),
- Neodymium magnets are characterized by highly resistant to demagnetization caused by external magnetic fields,
- By using a shiny coating of silver, the element gains an modern look,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of individual shaping and adjusting to concrete requirements,
- Huge importance in modern technologies – they are used in magnetic memories, drive modules, medical equipment, and modern systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in miniature devices
Limitations
- At very strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- 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 complex forms in magnets, we propose using casing - magnetic mount.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, small elements of these magnets can complicate diagnosis medical after entering the body.
- 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
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
- with a thickness minimum 10 mm
- with a plane perfectly flat
- under conditions of gap-free contact (metal-to-metal)
- for force applied at a right angle (pull-off, not shear)
- at conditions approx. 20°C
Determinants of practical lifting force of a magnet
- Gap (betwixt the magnet and the metal), as even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
- Angle of force application – maximum parameter is reached only during perpendicular pulling. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
- Material type – ideal substrate is pure iron steel. Hardened steels may have worse magnetic properties.
- Base smoothness – the smoother and more polished the surface, the larger the contact zone and stronger the hold. Roughness acts like micro-gaps.
- Thermal conditions – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular detachment force, in contrast under shearing force the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the holding force.
Safety rules for work with neodymium magnets
Warning for heart patients
For implant holders: Strong magnetic fields affect electronics. Keep at least 30 cm distance or request help to handle the magnets.
Cards and drives
Powerful magnetic fields can erase data on credit cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Handling guide
Use magnets consciously. Their huge power can surprise even experienced users. Plan your moves and do not underestimate their power.
Nickel allergy
A percentage of the population experience a sensitization to nickel, which is the standard coating for neodymium magnets. Frequent touching may cause an allergic reaction. We strongly advise wear protective gloves.
Danger to the youngest
Strictly keep magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are very dangerous.
Heat warning
Regular neodymium magnets (N-type) lose power when the temperature exceeds 80°C. Damage is permanent.
Material brittleness
Neodymium magnets are sintered ceramics, which means they are prone to chipping. Impact of two magnets will cause them cracking into shards.
Dust is flammable
Dust generated during cutting of magnets is self-igniting. Avoid drilling into magnets unless you are an expert.
Impact on smartphones
GPS units and mobile phones are extremely sensitive to magnetism. Close proximity with a powerful NdFeB magnet can ruin the internal compass in your phone.
Crushing force
Large magnets can crush fingers instantly. Do not put your hand between two strong magnets.
