Advantages and disadvantages of neodymium magnets.
Pros
- They do not lose power, even during approximately ten years – the reduction in lifting capacity is only ~1% (according to tests),
- Neodymium magnets remain extremely resistant to loss of magnetic properties caused by external magnetic fields,
- The use of an refined coating of noble metals (nickel, gold, silver) causes the element to have aesthetics,
- Magnets exhibit extremely high magnetic induction on the outer layer,
- Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
- Thanks to modularity in shaping and the ability to customize to complex applications,
- Wide application in electronics industry – they are utilized in magnetic memories, electric motors, advanced medical instruments, and multitasking production systems.
- Compactness – despite small sizes they provide effective action, making them ideal for precision applications
Disadvantages
- Brittleness is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
- Limited ability of producing nuts in the magnet and complex shapes - preferred is cover - mounting mechanism.
- Possible danger resulting from small fragments of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child health protection. It is also worth noting that tiny parts of these devices are able to disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Highest magnetic holding force – what it depends on?
- on a block made of structural steel, optimally conducting the magnetic field
- whose transverse dimension reaches at least 10 mm
- characterized by even structure
- without the slightest insulating layer between the magnet and steel
- under vertical application of breakaway force (90-degree angle)
- at ambient temperature room level
What influences lifting capacity in practice
- Distance (betwixt the magnet and the metal), since even a tiny clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
- Force direction – declared lifting capacity refers to pulling vertically. When attempting to slide, the magnet holds much less (typically approx. 20-30% of maximum force).
- Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Steel grade – ideal substrate is pure iron steel. Stainless steels may generate lower lifting capacity.
- Surface condition – smooth surfaces ensure maximum contact, which improves force. Uneven metal weaken the grip.
- Operating temperature – NdFeB sinters have a negative temperature coefficient. When it is hot they lose power, and at low temperatures gain strength (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of suitable thickness, under perpendicular forces, however under attempts to slide the magnet the holding force is lower. Additionally, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.
Safety rules for work with NdFeB magnets
Phone sensors
GPS units and mobile phones are extremely sensitive to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Thermal limits
Keep cool. NdFeB magnets are susceptible to temperature. If you require operation above 80°C, look for special high-temperature series (H, SH, UH).
Health Danger
Warning for patients: Strong magnetic fields disrupt electronics. Maintain at least 30 cm distance or request help to work with the magnets.
This is not a toy
Strictly keep magnets away from children. Choking hazard is significant, and the consequences of magnets connecting inside the body are tragic.
Eye protection
NdFeB magnets are sintered ceramics, meaning they are fragile like glass. Clashing of two magnets leads to them shattering into small pieces.
Fire warning
Fire hazard: Neodymium dust is highly flammable. Avoid machining magnets without safety gear as this may cause fire.
Warning for allergy sufferers
Studies show that the nickel plating (the usual finish) is a potent allergen. If you have an allergy, avoid touching magnets with bare hands or select coated magnets.
Bodily injuries
Big blocks can crush fingers in a fraction of a second. Do not place your hand betwixt two attracting surfaces.
Safe operation
Handle magnets consciously. Their huge power can surprise even experienced users. Plan your moves and respect their force.
Electronic hazard
Device Safety: Neodymium magnets can damage payment cards and sensitive devices (pacemakers, hearing aids, mechanical watches).
