Pros as well as cons of rare earth magnets.
Benefits
- Their strength is durable, and after approximately 10 years it decreases only by ~1% (theoretically),
- They have excellent resistance to magnetic field loss due to external magnetic sources,
- The use of an shiny finish of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
- Magnetic induction on the top side of the magnet turns out to be impressive,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Possibility of precise machining as well as modifying to concrete requirements,
- Significant place in innovative solutions – they find application in hard drives, electromotive mechanisms, medical equipment, as well as multitasking production systems.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which allows their use in small systems
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a special holder, which not only protects them against impacts but also raises their 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 and 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
- They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Limited possibility of producing threads in the magnet and complex shapes - recommended is a housing - magnetic holder.
- Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of child health protection. Additionally, small elements of these devices 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 can limit application in large quantities
Lifting parameters
Best holding force of the magnet in ideal parameters – what it depends on?
- on a block made of structural steel, optimally conducting the magnetic field
- possessing a massiveness of min. 10 mm to avoid saturation
- characterized by even structure
- with direct contact (no impurities)
- during pulling in a direction perpendicular to the plane
- at ambient temperature approx. 20 degrees Celsius
What influences lifting capacity in practice
- Distance – the presence of any layer (rust, dirt, air) interrupts the magnetic circuit, 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 drastically, often to levels of 20-30% of the nominal value.
- Substrate thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
- Material composition – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
- Thermal factor – hot environment weakens magnetic field. Too high temperature can permanently demagnetize the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the lifting capacity is smaller. Additionally, even a minimal clearance between the magnet and the plate lowers the load capacity.
Safety rules for work with neodymium magnets
Finger safety
Danger of trauma: The pulling power is so immense that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
Handling rules
Handle magnets consciously. Their immense force can surprise even experienced users. Plan your moves and do not underestimate their power.
Keep away from children
Always store magnets out of reach of children. Ingestion danger is high, and the consequences of magnets connecting inside the body are very dangerous.
Mechanical processing
Combustion risk: Rare earth powder is explosive. Do not process magnets in home conditions as this may cause fire.
Keep away from computers
Do not bring magnets near a wallet, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
Material brittleness
Protect your eyes. Magnets can explode upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.
Impact on smartphones
Navigation devices and smartphones are extremely sensitive to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Implant safety
Individuals with a heart stimulator should keep an large gap from magnets. The magnetic field can interfere with the operation of the life-saving device.
Skin irritation risks
Studies show that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, refrain from touching magnets with bare hands or choose encased magnets.
Heat sensitivity
Standard neodymium magnets (N-type) lose magnetization when the temperature surpasses 80°C. The loss of strength is permanent.
