Advantages and disadvantages of neodymium magnets.
Advantages
- They have constant strength, and over nearly ten years their performance decreases symbolically – ~1% (according to theory),
- Magnets perfectly protect themselves against demagnetization caused by foreign field sources,
- By applying a lustrous coating of silver, the element acquires an proper look,
- Magnetic induction on the working part of the magnet remains extremely intense,
- 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 customize to unusual requirements,
- Significant place in advanced technology sectors – they serve a role in hard drives, electric drive systems, medical equipment, also complex engineering applications.
- Thanks to their power density, small magnets offer high operating force, occupying minimum space,
Limitations
- Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a strong case, which not only protects them against impacts but also raises their durability
- We warn that neodymium magnets can reduce 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 advise using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing threads and complex shapes in magnets, we recommend using casing - magnetic mount.
- Possible danger resulting from small fragments of magnets are risky, in case of ingestion, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these products are able to be problematic in diagnostics medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Lifting parameters
Maximum lifting capacity of the magnet – what contributes to it?
- on a block made of mild steel, perfectly concentrating the magnetic field
- whose transverse dimension reaches at least 10 mm
- with an ideally smooth contact surface
- without any insulating layer between the magnet and steel
- for force acting at a right angle (in the magnet axis)
- at temperature room level
Practical lifting capacity: influencing factors
- Clearance – the presence of foreign body (rust, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
- Load vector – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is usually many times smaller (approx. 1/5 of the lifting capacity).
- Substrate thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
- Metal type – different alloys attracts identically. Alloy additives weaken the attraction effect.
- Plate texture – smooth surfaces ensure maximum contact, which increases force. Uneven metal weaken the grip.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet and the plate decreases the lifting capacity.
H&S for magnets
Data carriers
Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Keep a distance of min. 10 cm.
Risk of cracking
Neodymium magnets are sintered ceramics, which means they are fragile like glass. Collision of two magnets will cause them cracking into small pieces.
Flammability
Machining of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is hard to extinguish.
Danger to pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Precision electronics
An intense magnetic field interferes with the operation of compasses in smartphones and navigation systems. Maintain magnets close to a smartphone to prevent breaking the sensors.
Product not for children
These products are not suitable for play. Swallowing a few magnets may result in them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.
Warning for allergy sufferers
It is widely known that the nickel plating (standard magnet coating) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands and choose encased magnets.
Handling guide
Be careful. Neodymium magnets act from a distance and connect with huge force, often quicker than you can move away.
Thermal limits
Standard neodymium magnets (N-type) lose magnetization when the temperature goes above 80°C. Damage is permanent.
Bodily injuries
Watch your fingers. Two large magnets will snap together immediately with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!
