Strengths as well as weaknesses of rare earth magnets.
Advantages
- They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They feature excellent resistance to weakening of magnetic properties due to opposing magnetic fields,
- The use of an metallic layer of noble metals (nickel, gold, silver) causes the element to present itself better,
- Neodymium magnets generate maximum magnetic induction on a small area, which allows for strong attraction,
- Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
- Due to the option of precise molding and adaptation to individualized projects, neodymium magnets can be created in a wide range of forms and dimensions, which makes them more universal,
- Fundamental importance in future technologies – they serve a role in magnetic memories, motor assemblies, diagnostic systems, also other advanced devices.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in small systems
Limitations
- At strong impacts they can crack, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's 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.
- They oxidize in a humid environment - during use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
- We recommend casing - magnetic mount, due to difficulties in creating threads inside the magnet and complicated shapes.
- Potential hazard to health – tiny shards of magnets are risky, if swallowed, which gains importance in the context of child health protection. Furthermore, small elements of these devices are able to disrupt the diagnostic process medical after entering the body.
- With large orders the cost of neodymium magnets is a challenge,
Holding force characteristics
Highest magnetic holding force – what it depends on?
- on a plate made of structural steel, effectively closing the magnetic field
- with a cross-section no less than 10 mm
- with a surface perfectly flat
- with zero gap (without coatings)
- during detachment in a direction vertical to the plane
- at ambient temperature room level
What influences lifting capacity in practice
- Distance – the presence of foreign body (rust, dirt, air) acts as an insulator, which reduces capacity steeply (even by 50% at 0.5 mm).
- Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is usually many times smaller (approx. 1/5 of the lifting capacity).
- Wall thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Metal type – different alloys attracts identically. High carbon content worsen the attraction effect.
- Surface finish – full contact is possible only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature influence – hot environment weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.
Lifting capacity was assessed with the use of a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under shearing force the holding force is lower. Moreover, even a minimal clearance between the magnet and the plate decreases the holding force.
Safe handling of NdFeB magnets
Maximum temperature
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and pulling force.
Cards and drives
Equipment safety: Strong magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).
Implant safety
Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have electronic implants.
Material brittleness
Despite the nickel coating, the material is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.
Metal Allergy
Nickel alert: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction appears, cease handling magnets and use protective gear.
Keep away from electronics
Remember: neodymium magnets produce a field that confuses precision electronics. Keep a separation from your mobile, tablet, and GPS.
Fire risk
Machining of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Respect the power
Use magnets consciously. Their powerful strength can shock even experienced users. Be vigilant and respect their power.
Hand protection
Large magnets can break fingers in a fraction of a second. Never place your hand between two strong magnets.
Swallowing risk
Always keep magnets away from children. Risk of swallowing is high, and the consequences of magnets clamping inside the body are fatal.
