Strengths as well as weaknesses of Nd2Fe14B magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (in laboratory conditions),
- Magnets effectively defend themselves against loss of magnetization caused by foreign field sources,
- By using a smooth coating of gold, the element acquires an nice look,
- Magnets are distinguished by very high magnetic induction on the active area,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures approaching 230°C and above...
- Thanks to freedom in designing and the ability to modify to unusual requirements,
- Wide application in modern industrial fields – they are utilized in HDD drives, electric motors, precision medical tools, and technologically advanced constructions.
- Thanks to concentrated force, small magnets offer high operating force, with minimal size,
Limitations
- At strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
- When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as 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 advise using waterproof magnets made of rubber, plastic or other material resistant to moisture, when using outdoors
- Limited possibility of producing threads in the magnet and complex shapes - recommended is cover - magnet mounting.
- Possible danger resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these magnets can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Detachment force of the magnet in optimal conditions – what it depends on?
- using a base made of high-permeability steel, acting as a ideal flux conductor
- with a thickness of at least 10 mm
- characterized by smoothness
- under conditions of ideal adhesion (metal-to-metal)
- for force acting at a right angle (in the magnet axis)
- in temp. approx. 20°C
Key elements affecting lifting force
- Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Loading method – catalog parameter refers to detachment vertically. When slipping, the magnet holds much less (typically approx. 20-30% of maximum force).
- Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Material type – ideal substrate is high-permeability steel. Hardened steels may generate lower lifting capacity.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Temperature influence – high temperature weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was determined with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under attempts to slide the magnet the holding force is lower. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with NdFeB magnets
Protective goggles
Beware of splinters. Magnets can explode upon violent connection, ejecting shards into the air. We recommend safety glasses.
Safe distance
Avoid bringing magnets close to a wallet, computer, or TV. The magnetic field can irreversibly ruin these devices and erase data from cards.
Heat warning
Keep cool. NdFeB magnets are sensitive to temperature. If you require operation above 80°C, ask us about special high-temperature series (H, SH, UH).
Safe operation
Handle with care. Neodymium magnets act from a long distance and snap with massive power, often faster than you can move away.
Crushing risk
Protect your hands. Two powerful magnets will join instantly with a force of massive weight, crushing everything in their path. Be careful!
GPS and phone interference
Remember: rare earth magnets generate a field that disrupts sensitive sensors. Maintain a separation from your phone, device, and GPS.
Medical implants
For implant holders: Powerful magnets affect medical devices. Maintain at least 30 cm distance or ask another person to handle the magnets.
Product not for children
Only for adults. Small elements pose a choking risk, causing serious injuries. Keep out of reach of children and animals.
Skin irritation risks
Studies show that the nickel plating (standard magnet coating) is a potent allergen. If you have an allergy, avoid direct skin contact or opt for encased magnets.
Flammability
Mechanical processing of NdFeB material poses a fire risk. Magnetic powder reacts violently with oxygen and is hard to extinguish.
