Advantages and disadvantages of neodymium magnets.
Advantages
- They have constant strength, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- Magnets very well protect themselves against demagnetization caused by external fields,
- In other words, due to the smooth finish of silver, the element gains a professional look,
- They are known for high magnetic induction at the operating surface, which increases their power,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
- Possibility of individual forming and adjusting to individual conditions,
- Huge importance in high-tech industry – they find application in hard drives, brushless drives, precision medical tools, and complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Disadvantages
- At very strong impacts they can crack, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 extremely resistant to heat
- They rust in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated forms.
- Potential hazard resulting from small fragments of magnets are risky, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small elements of these devices are able to complicate diagnosis medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Lifting parameters
Best holding force of the magnet in ideal parameters – what contributes to it?
- using a base made of mild steel, serving as a magnetic yoke
- with a cross-section no less than 10 mm
- with an polished touching surface
- without any clearance between the magnet and steel
- during pulling in a direction vertical to the mounting surface
- at conditions approx. 20°C
Determinants of lifting force in real conditions
- Air gap (betwixt the magnet and the metal), because even a microscopic distance (e.g. 0.5 mm) can cause a reduction in force by up to 50% (this also applies to varnish, corrosion or dirt).
- Loading method – catalog parameter refers to pulling vertically. When slipping, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
- Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
- Chemical composition of the base – low-carbon steel attracts best. Alloy steels lower magnetic properties and lifting capacity.
- Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal weaken the grip.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet and the plate decreases the load capacity.
Precautions when working with neodymium magnets
Physical harm
Protect your hands. Two powerful magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Flammability
Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
GPS Danger
GPS units and mobile phones are extremely susceptible to magnetism. Close proximity with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Nickel allergy
Certain individuals have a contact allergy to nickel, which is the typical protective layer for NdFeB magnets. Prolonged contact might lead to skin redness. We suggest use safety gloves.
Demagnetization risk
Monitor thermal conditions. Heating the magnet to high heat will destroy its properties and strength.
Keep away from computers
Avoid bringing magnets close to a wallet, laptop, or screen. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Caution required
Use magnets with awareness. Their huge power can shock even experienced users. Stay alert and respect their power.
Magnet fragility
Beware of splinters. Magnets can fracture upon uncontrolled impact, launching sharp fragments into the air. We recommend safety glasses.
Choking Hazard
These products are not toys. Swallowing several magnets may result in them pinching intestinal walls, which poses a critical condition and necessitates immediate surgery.
Medical implants
People with a heart stimulator should maintain an absolute distance from magnets. The magnetism can disrupt the operation of the life-saving device.
