Pros and cons of rare earth magnets.
Advantages
- Their strength remains stable, and after around ten years it decreases only by ~1% (according to research),
- Magnets effectively protect themselves against demagnetization caused by ambient magnetic noise,
- A magnet with a smooth silver surface looks better,
- Neodymium magnets create maximum magnetic induction on a their surface, which allows for strong attraction,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Considering the possibility of flexible forming and adaptation to unique projects, neodymium magnets can be created in a variety of geometric configurations, which increases their versatility,
- Fundamental importance in modern industrial fields – they serve a role in hard drives, electric drive systems, diagnostic systems, and industrial machines.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which enables their usage in miniature devices
Cons
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a steel housing, 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 suggest our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in producing nuts and complicated forms in magnets, we propose using casing - magnetic mount.
- Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which gains importance in the context of child safety. Additionally, tiny parts of these products are able to be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting capacity of the magnet – what it depends on?
- with the application of a sheet made of low-carbon steel, ensuring full magnetic saturation
- possessing a massiveness of at least 10 mm to avoid saturation
- with a plane perfectly flat
- without the slightest insulating layer between the magnet and steel
- during detachment in a direction perpendicular to the plane
- at standard ambient temperature
Lifting capacity in practice – influencing factors
- Clearance – the presence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces power steeply (even by 50% at 0.5 mm).
- Force direction – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of converting into lifting capacity.
- Material type – ideal substrate is high-permeability steel. Stainless steels may attract less.
- Plate texture – ground elements guarantee perfect abutment, which improves field saturation. Uneven metal weaken the grip.
- Temperature influence – hot environment weakens pulling force. Exceeding the limit temperature can permanently damage the magnet.
Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, however under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet’s surface and the plate lowers the holding force.
Precautions when working with neodymium magnets
Dust explosion hazard
Mechanical processing of neodymium magnets carries a risk of fire hazard. Neodymium dust reacts violently with oxygen and is hard to extinguish.
Skin irritation risks
Studies show that nickel (standard magnet coating) is a strong allergen. If you have an allergy, avoid touching magnets with bare hands or choose versions in plastic housing.
Do not give to children
Neodymium magnets are not toys. Eating multiple magnets may result in them pinching intestinal walls, which poses a direct threat to life and necessitates immediate surgery.
Data carriers
Do not bring magnets close to a wallet, laptop, or TV. The magnetic field can irreversibly ruin these devices and wipe information from cards.
Health Danger
For implant holders: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to work with the magnets.
Demagnetization risk
Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its properties and pulling force.
Do not underestimate power
Use magnets with awareness. Their immense force can surprise even professionals. Plan your moves and do not underestimate their power.
Compass and GPS
A strong magnetic field interferes with the functioning of compasses in phones and navigation systems. Do not bring magnets close to a device to avoid breaking the sensors.
Eye protection
NdFeB magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets leads to them breaking into shards.
Finger safety
Pinching hazard: The attraction force is so immense that it can result in blood blisters, pinching, and broken bones. Use thick gloves.
