Strengths and weaknesses of rare earth magnets.
Advantages
- They virtually do not lose strength, because even after 10 years the performance loss is only ~1% (according to literature),
- They have excellent resistance to magnetism drop when exposed to opposing magnetic fields,
- Thanks to the shimmering finish, the surface of nickel, gold-plated, or silver-plated gives an elegant appearance,
- Neodymium magnets deliver maximum magnetic induction on a small surface, which allows for strong attraction,
- Thanks to resistance to high temperature, they can operate (depending on the form) even at temperatures up to 230°C and higher...
- Possibility of individual creating as well as adjusting to defined applications,
- Huge importance in advanced technology sectors – they are utilized in hard drives, motor assemblies, medical devices, also industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, occupying minimum space,
Disadvantages
- Brittleness is one of their disadvantages. Upon strong impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
- We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
- Due to limitations in producing nuts and complex forms in magnets, we recommend using a housing - magnetic mount.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which is particularly important in the context of child safety. Furthermore, small elements of these devices can disrupt the diagnostic process medical after entering the body.
- Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications
Holding force characteristics
Maximum holding power of the magnet – what affects it?
- on a block made of mild steel, effectively closing the magnetic flux
- whose transverse dimension reaches at least 10 mm
- characterized by smoothness
- with total lack of distance (no coatings)
- under axial force direction (90-degree angle)
- at temperature approx. 20 degrees Celsius
Practical lifting capacity: influencing factors
- Air gap (between the magnet and the plate), as even a microscopic clearance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to paint, corrosion or debris).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin sheet does not close the flux, causing part of the power to be lost to the other side.
- Material composition – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
- Surface finish – full contact is possible only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Temperature influence – high temperature reduces pulling force. Too high temperature can permanently damage the magnet.
Lifting capacity testing was performed on a smooth plate of suitable thickness, under a perpendicular pulling force, however under shearing force the holding force is lower. In addition, even a small distance between the magnet’s surface and the plate lowers the load capacity.
Safety rules for work with NdFeB magnets
Permanent damage
Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its properties and strength.
Do not give to children
These products are not intended for children. Swallowing multiple magnets can lead to them attracting across intestines, which poses a critical condition and requires urgent medical intervention.
Bone fractures
Big blocks can break fingers in a fraction of a second. Do not put your hand betwixt two attracting surfaces.
Medical implants
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.
Safe distance
Do not bring magnets close to a wallet, computer, or TV. The magnetic field can permanently damage these devices and wipe information from cards.
Risk of cracking
Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets leads to them shattering into shards.
Caution required
Before use, read the rules. Uncontrolled attraction can break the magnet or injure your hand. Be predictive.
Sensitization to coating
A percentage of the population experience a hypersensitivity to nickel, which is the common plating for neodymium magnets. Extended handling may cause an allergic reaction. We strongly advise use safety gloves.
Impact on smartphones
Navigation devices and mobile phones are highly sensitive to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the internal compass in your phone.
Flammability
Machining of NdFeB material poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.
