Advantages as well as disadvantages of neodymium magnets.
Benefits
- Their power is maintained, and after approximately 10 years it drops only by ~1% (theoretically),
- They feature excellent resistance to magnetic field loss as a result of external magnetic sources,
- A magnet with a metallic nickel surface has better aesthetics,
- They show high magnetic induction at the operating surface, which affects their effectiveness,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
- Possibility of individual forming as well as adjusting to individual applications,
- Significant place in innovative solutions – they serve a role in mass storage devices, electric drive systems, precision medical tools, and complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which makes them useful in small systems
Disadvantages
- Brittleness 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
- Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are extremely resistant to heat
- Magnets exposed to a humid environment can rust. Therefore during using outdoors, we suggest using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating threads and complicated shapes in magnets, we recommend using casing - magnetic holder.
- Health risk to health – tiny shards of magnets can be dangerous, when accidentally swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these devices are able to be problematic in diagnostics medical after entering the body.
- High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – what it depends on?
- using a base made of high-permeability steel, acting as a circuit closing element
- whose transverse dimension equals approx. 10 mm
- with a surface perfectly flat
- with zero gap (no paint)
- during pulling in a direction vertical to the mounting surface
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Clearance – existence of foreign body (paint, dirt, air) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – insufficiently thick steel does not accept the full field, causing part of the power to be wasted into the air.
- Material composition – not every steel reacts the same. Alloy additives worsen the attraction effect.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces reduce efficiency.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the thermal limit for a given model.
Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, however under parallel forces the lifting capacity is smaller. Additionally, even a small distance between the magnet and the plate reduces the holding force.
Safe handling of NdFeB magnets
Sensitization to coating
Medical facts indicate that nickel (standard magnet coating) is a common allergen. For allergy sufferers, avoid touching magnets with bare hands and choose versions in plastic housing.
Threat to navigation
GPS units and smartphones are highly susceptible to magnetic fields. Direct contact with a strong magnet can decalibrate the sensors in your phone.
Pinching danger
Pinching hazard: The attraction force is so great that it can result in hematomas, pinching, and even bone fractures. Use thick gloves.
No play value
NdFeB magnets are not intended for children. Eating several magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires urgent medical intervention.
Pacemakers
Life threat: Strong magnets can turn off heart devices and defibrillators. Stay away if you have medical devices.
Fragile material
Despite the nickel coating, neodymium is delicate and not impact-resistant. Do not hit, as the magnet may crumble into sharp, dangerous pieces.
Heat warning
Keep cool. NdFeB magnets are susceptible to heat. If you need operation above 80°C, inquire about special high-temperature series (H, SH, UH).
Flammability
Dust produced during cutting of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.
Cards and drives
Device Safety: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
Do not underestimate power
Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and respect their power.
