Strengths and weaknesses of neodymium magnets.
Strengths
- They virtually do not lose power, because even after ten years the performance loss is only ~1% (based on calculations),
- They possess excellent resistance to magnetic field loss as a result of external magnetic sources,
- In other words, due to the metallic finish of gold, the element looks attractive,
- Magnets exhibit huge magnetic induction on the surface,
- Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the form) even at a temperature of 230°C or more...
- Possibility of detailed machining as well as adjusting to defined needs,
- Huge importance in modern industrial fields – they find application in data components, drive modules, advanced medical instruments, and multitasking production systems.
- Thanks to concentrated force, small magnets offer high operating force, in miniature format,
Disadvantages
- To avoid cracks upon strong impacts, we suggest using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in producing threads and complicated shapes in magnets, we propose using a housing - magnetic mount.
- Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. Additionally, small components of these magnets can disrupt the diagnostic process medical in case of swallowing.
- High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities
Pull force analysis
Best holding force of the magnet in ideal parameters – 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
- characterized by even structure
- without any air gap between the magnet and steel
- for force acting at a right angle (pull-off, not shear)
- in stable room temperature
Practical lifting capacity: influencing factors
- Distance (between the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) results in a reduction in force by up to 50% (this also applies to paint, corrosion or debris).
- Loading method – catalog parameter refers to pulling vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of generating force.
- Metal type – not every steel reacts the same. Alloy additives weaken the attraction effect.
- Plate texture – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
- Thermal factor – hot environment reduces pulling force. Exceeding the limit temperature can permanently damage the magnet.
Holding force was measured on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the load capacity.
Warnings
Do not give to children
Adult use only. Tiny parts pose a choking risk, causing severe trauma. Store away from kids and pets.
Pinching danger
Big blocks can smash fingers in a fraction of a second. Never place your hand between two attracting surfaces.
Precision electronics
A strong magnetic field disrupts the functioning of compasses in smartphones and GPS navigation. Do not bring magnets close to a smartphone to prevent damaging the sensors.
Implant safety
People with a pacemaker must keep an large gap from magnets. The magnetic field can stop the functioning of the life-saving device.
Threat to electronics
Equipment safety: Strong magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).
Metal Allergy
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If redness occurs, cease handling magnets and wear gloves.
Safe operation
Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.
Maximum temperature
Control the heat. Heating the magnet to high heat will permanently weaken its magnetic structure and strength.
Do not drill into magnets
Powder produced during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.
Magnets are brittle
NdFeB magnets are ceramic materials, which means they are fragile like glass. Clashing of two magnets leads to them cracking into shards.
