Pros and cons of Nd2Fe14B magnets.
Strengths
- Their magnetic field remains stable, and after approximately ten years it drops only by ~1% (theoretically),
- Neodymium magnets remain remarkably resistant to demagnetization caused by external field sources,
- A magnet with a metallic gold surface is more attractive,
- Neodymium magnets ensure maximum magnetic induction on a small surface, which allows for strong attraction,
- Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
- Possibility of detailed machining as well as adapting to individual conditions,
- Versatile presence in electronics industry – they are commonly used in HDD drives, electric motors, advanced medical instruments, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which makes them useful in compact constructions
Cons
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- Neodymium magnets lose their force 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
- Due to the susceptibility of magnets to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
- Due to limitations in creating nuts and complex forms in magnets, we recommend using casing - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child health protection. Furthermore, small elements of these products are able to complicate diagnosis medical in case of swallowing.
- Due to complex production process, their price is higher than average,
Pull force analysis
Maximum holding power of the magnet – what contributes to it?
- on a base made of mild steel, effectively closing the magnetic field
- with a thickness minimum 10 mm
- with an ideally smooth contact surface
- under conditions of ideal adhesion (surface-to-surface)
- during detachment in a direction perpendicular to the mounting surface
- at temperature room level
Practical lifting capacity: influencing factors
- Distance – the presence of any layer (paint, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
- Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
- Steel thickness – too thin steel causes magnetic saturation, causing part of the flux to be escaped into the air.
- Material type – ideal substrate is pure iron steel. Hardened steels may generate lower lifting capacity.
- Base smoothness – the more even the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
- Temperature – temperature increase causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.
Holding force was measured on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Warnings
Respect the power
Be careful. Rare earth magnets attract from a distance and connect with massive power, often quicker than you can move away.
Bone fractures
Protect your hands. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Compass and GPS
Navigation devices and mobile phones are highly sensitive to magnetic fields. Close proximity with a strong magnet can decalibrate the sensors in your phone.
Mechanical processing
Drilling and cutting of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.
Heat sensitivity
Control the heat. Exposing the magnet to high heat will permanently weaken its properties and strength.
Life threat
Health Alert: Strong magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.
Cards and drives
Avoid bringing magnets close to a purse, computer, or TV. The magnetic field can destroy these devices and erase data from cards.
Allergic reactions
Warning for allergy sufferers: The Ni-Cu-Ni coating contains nickel. If an allergic reaction happens, cease working with magnets and use protective gear.
Eye protection
Despite the nickel coating, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into hazardous fragments.
Choking Hazard
NdFeB magnets are not suitable for play. Eating a few magnets can lead to them pinching intestinal walls, which constitutes a critical condition and requires urgent medical intervention.
