Strengths and weaknesses of rare earth magnets.
Pros
- They retain magnetic properties for almost ten years – the drop is just ~1% (according to analyses),
- They do not lose their magnetic properties even under strong external field,
- A magnet with a shiny silver surface has better aesthetics,
- Magnetic induction on the working layer of the magnet remains maximum,
- Through (adequate) combination of ingredients, they can achieve high thermal strength, allowing for action at temperatures reaching 230°C and above...
- In view of the possibility of flexible shaping and adaptation to individualized solutions, NdFeB magnets can be created in a wide range of geometric configurations, which amplifies use scope,
- Key role in high-tech industry – they serve a role in magnetic memories, motor assemblies, medical equipment, also technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in small systems
Limitations
- At strong impacts they can break, therefore we advise placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's 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 when using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material resistant to moisture
- We suggest casing - magnetic mount, due to difficulties in realizing threads inside the magnet and complicated forms.
- Possible danger resulting from small fragments of magnets pose a threat, if swallowed, which becomes key in the context of child health protection. Additionally, small components of these magnets can disrupt the diagnostic process medical when they are in the body.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Maximum holding power of the magnet – what it depends on?
- on a base made of mild steel, effectively closing the magnetic field
- possessing a thickness of min. 10 mm to avoid saturation
- with a surface perfectly flat
- without any air gap between the magnet and steel
- for force applied at a right angle (pull-off, not shear)
- at room temperature
Determinants of practical lifting force of a magnet
- Distance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity steeply (even by 50% at 0.5 mm).
- Loading method – catalog parameter refers to pulling vertically. When applying parallel force, the magnet holds significantly lower power (often approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Part of the magnetic field passes through the material instead of generating force.
- Plate material – mild steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
- Base smoothness – the smoother and more polished the plate, the better the adhesion and stronger the hold. Unevenness creates an air distance.
- Temperature influence – high temperature reduces magnetic field. Too high temperature can permanently damage the magnet.
Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under shearing force the load capacity is reduced by as much as fivefold. In addition, even a small distance between the magnet’s surface and the plate decreases the holding force.
Precautions when working with NdFeB magnets
Threat to electronics
Intense magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
Safe operation
Handle magnets consciously. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their force.
Pacemakers
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
Skin irritation risks
It is widely known that the nickel plating (standard magnet coating) is a common allergen. If you have an allergy, prevent direct skin contact and choose encased magnets.
Risk of cracking
Protect your eyes. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Wear goggles.
Serious injuries
Watch your fingers. Two large magnets will join instantly with a force of massive weight, destroying anything in their path. Be careful!
No play value
Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Store out of reach of kids and pets.
Impact on smartphones
GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a strong magnet can decalibrate the internal compass in your phone.
Heat sensitivity
Control the heat. Exposing the magnet to high heat will ruin its properties and pulling force.
Mechanical processing
Mechanical processing of neodymium magnets poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.
