Advantages as well as disadvantages of neodymium magnets.
Pros
- They have stable power, and over more than ten years their performance decreases symbolically – ~1% (in testing),
- They are resistant to demagnetization induced by presence of other magnetic fields,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Neodymium magnets achieve maximum magnetic induction on a contact point, which allows for strong attraction,
- Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Thanks to versatility in shaping and the capacity to modify to client solutions,
- Universal use in modern industrial fields – they serve a role in computer drives, motor assemblies, advanced medical instruments, and modern systems.
- Thanks to their power density, small magnets offer high operating force, in miniature format,
Limitations
- To avoid cracks under impact, we recommend using special steel housings. Such a solution secures the magnet and simultaneously increases its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as 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 rust in a humid environment. For use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- Due to limitations in producing threads and complex shapes in magnets, we propose using casing - magnetic holder.
- Possible danger to health – tiny shards of magnets can be dangerous, in case of ingestion, which gains importance in the context of child health protection. Additionally, small components of these devices can complicate diagnosis medical in case of swallowing.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Lifting parameters
Highest magnetic holding force – what it depends on?
- using a base made of high-permeability steel, serving as a ideal flux conductor
- with a thickness no less than 10 mm
- characterized by smoothness
- with zero gap (no impurities)
- under perpendicular force vector (90-degree angle)
- at temperature approx. 20 degrees Celsius
Lifting capacity in practice – influencing factors
- Distance (betwixt the magnet and the metal), because even a tiny clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
- Force direction – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits much less (typically approx. 20-30% of maximum force).
- Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux penetrates through instead of converting into lifting capacity.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
- Thermal factor – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, whereas under attempts to slide the magnet the load capacity is reduced by as much as 75%. Moreover, even a small distance between the magnet and the plate reduces the lifting capacity.
Precautions when working with neodymium magnets
Power loss in heat
Avoid heat. Neodymium magnets are sensitive to heat. If you need operation above 80°C, look for HT versions (H, SH, UH).
Do not underestimate power
Use magnets with awareness. Their powerful strength can shock even experienced users. Plan your moves and respect their force.
Threat to navigation
A strong magnetic field interferes with the functioning of magnetometers in smartphones and GPS navigation. Maintain magnets close to a device to avoid breaking the sensors.
Warning for allergy sufferers
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness happens, cease working with magnets and use protective gear.
Fragile material
Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Eye protection is mandatory.
Keep away from computers
Data protection: Neodymium magnets can ruin data carriers and delicate electronics (heart implants, hearing aids, mechanical watches).
Medical interference
For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or request help to work with the magnets.
Dust is flammable
Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.
Bone fractures
Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Danger to the youngest
Adult use only. Small elements can be swallowed, causing severe trauma. Store out of reach of kids and pets.
