Advantages as well as disadvantages of rare earth magnets.
Benefits
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- They retain their magnetic properties even under strong external field,
- In other words, due to the metallic finish of nickel, the element looks attractive,
- The surface of neodymium magnets generates a powerful magnetic field – this is a distinguishing feature,
- 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 machining and adjusting to defined requirements,
- Key role in innovative solutions – they find application in HDD drives, motor assemblies, diagnostic systems, and other advanced devices.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Cons
- Brittleness is one of their disadvantages. Upon intense impact they can fracture. We recommend keeping them in a special holder, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
- They oxidize in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend cover - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
- Potential hazard related to microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of child safety. Furthermore, tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- With mass production the cost of neodymium magnets can be a barrier,
Holding force characteristics
Best holding force of the magnet in ideal parameters – what contributes to it?
- with the use of a sheet made of low-carbon steel, ensuring full magnetic saturation
- whose transverse dimension reaches at least 10 mm
- with a surface free of scratches
- with direct contact (no paint)
- during detachment in a direction vertical to the mounting surface
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Gap between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer 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 holds significantly lower power (typically approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field penetrates through instead of generating force.
- Material composition – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Surface condition – smooth surfaces ensure maximum contact, which increases field saturation. Uneven metal reduce efficiency.
- Operating temperature – neodymium magnets have a sensitivity to temperature. When it is hot they are weaker, and in frost gain strength (up to a certain limit).
Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.
Precautions when working with neodymium magnets
Thermal limits
Monitor thermal conditions. Exposing the magnet to high heat will ruin its magnetic structure and pulling force.
Warning for heart patients
Patients with a ICD should keep an absolute distance from magnets. The magnetism can disrupt the functioning of the implant.
Safe operation
Handle with care. Rare earth magnets act from a long distance and connect with massive power, often faster than you can react.
Protective goggles
NdFeB magnets are ceramic materials, meaning they are very brittle. Collision of two magnets leads to them shattering into shards.
Dust is flammable
Powder generated during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Sensitization to coating
Some people have a hypersensitivity to Ni, which is the typical protective layer for neodymium magnets. Prolonged contact may cause dermatitis. We suggest use protective gloves.
Keep away from electronics
Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Danger to the youngest
Absolutely store magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are tragic.
Crushing force
Danger of trauma: The attraction force is so great that it can cause blood blisters, pinching, and even bone fractures. Protective gloves are recommended.
Cards and drives
Avoid bringing magnets close to a purse, computer, or screen. The magnetism can permanently damage these devices and wipe information from cards.
