Strengths and weaknesses of neodymium magnets.
Strengths
- Their power is durable, and after around ten years it decreases only by ~1% (theoretically),
- Neodymium magnets are characterized by remarkably resistant to magnetic field loss caused by external interference,
- By applying a smooth coating of nickel, the element acquires an nice look,
- Magnets are distinguished by excellent magnetic induction on the outer layer,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
- Due to the potential of precise molding and adaptation to unique needs, magnetic components can be produced in a broad palette of forms and dimensions, which makes them more universal,
- Fundamental importance in modern industrial fields – they find application in HDD drives, drive modules, advanced medical instruments, as well as multitasking production systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- At very strong impacts they can break, therefore we recommend placing them in steel cases. A metal housing provides additional protection against damage, as well as increases the magnet's durability.
- Neodymium magnets decrease their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
- Due to limitations in realizing nuts and complex shapes in magnets, we propose using a housing - magnetic holder.
- Health risk to health – tiny shards of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that small elements of these devices can be problematic in diagnostics medical in case of swallowing.
- Due to expensive raw materials, their price is higher than average,
Lifting parameters
Magnetic strength at its maximum – what affects it?
- with the use of a yoke made of special test steel, ensuring maximum field concentration
- whose thickness equals approx. 10 mm
- with a plane free of scratches
- without the slightest insulating layer between the magnet and steel
- under axial force direction (90-degree angle)
- at standard ambient temperature
Impact of factors on magnetic holding capacity in practice
- Distance – existence of any layer (rust, tape, gap) 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 holding force drops significantly, often to levels of 20-30% of the nominal value.
- Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
- Steel grade – the best choice is pure iron steel. Hardened steels may attract less.
- Surface finish – full contact is obtained only on polished steel. Any scratches and bumps reduce the real contact area, reducing force.
- Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).
Lifting capacity was assessed by applying a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate lowers the holding force.
Warnings
Serious injuries
Watch your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!
Material brittleness
NdFeB magnets are sintered ceramics, which means they are very brittle. Clashing of two magnets will cause them cracking into shards.
Conscious usage
Before use, read the rules. Sudden snapping can break the magnet or hurt your hand. Think ahead.
Electronic hazard
Do not bring magnets close to a purse, laptop, or screen. The magnetism can irreversibly ruin these devices and erase data from cards.
Choking Hazard
Neodymium magnets are not suitable for play. Accidental ingestion of several magnets may result in them attracting across intestines, which poses a direct threat to life and necessitates urgent medical intervention.
Machining danger
Fire hazard: Rare earth powder is explosive. Avoid machining magnets in home conditions as this may cause fire.
Medical interference
Medical warning: Neodymium magnets can turn off heart devices and defibrillators. Stay away if you have electronic implants.
Demagnetization risk
Monitor thermal conditions. Heating the magnet to high heat will ruin its magnetic structure and pulling force.
Compass and GPS
A powerful magnetic field disrupts the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a smartphone to avoid damaging the sensors.
Warning for allergy sufferers
It is widely known that nickel (standard magnet coating) is a potent allergen. For allergy sufferers, prevent touching magnets with bare hands and choose versions in plastic housing.
