Pros as well as cons of Nd2Fe14B magnets.
Pros
- Their power is durable, and after around ten years it drops only by ~1% (according to research),
- They feature excellent resistance to weakening of magnetic properties when exposed to external fields,
- By using a decorative coating of gold, the element has an proper look,
- They are known for high magnetic induction at the operating surface, which improves attraction properties,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
- Thanks to freedom in shaping and the ability to adapt to complex applications,
- Significant place in innovative solutions – they are used in magnetic memories, brushless drives, precision medical tools, and technologically advanced constructions.
- Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in small dimensions, which makes them useful in small systems
Cons
- They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
- When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their strength 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
- Limited ability of producing nuts in the magnet and complicated forms - preferred is a housing - magnet mounting.
- Possible danger to health – tiny shards of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. It is also worth noting that tiny parts of these magnets can be problematic in diagnostics medical when they are in 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
Maximum magnetic pulling force – what affects it?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- possessing a massiveness of minimum 10 mm to avoid saturation
- with a surface perfectly flat
- with zero gap (no impurities)
- during pulling in a direction perpendicular to the mounting surface
- at standard ambient temperature
Impact of factors on magnetic holding capacity in practice
- Distance (between the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) results in a reduction in lifting capacity by up to 50% (this also applies to varnish, rust or dirt).
- Pull-off angle – remember that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
- Metal thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field passes through the material instead of generating force.
- Material type – the best choice is high-permeability steel. Hardened steels may attract less.
- Surface condition – ground elements guarantee perfect abutment, which increases field saturation. Uneven metal reduce efficiency.
- Thermal environment – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.
Holding force was checked on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under parallel forces the lifting capacity is smaller. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.
H&S for magnets
Danger to the youngest
Strictly store magnets away from children. Risk of swallowing is significant, and the effects of magnets connecting inside the body are tragic.
Fire warning
Powder produced during grinding of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Magnetic interference
GPS units and smartphones are extremely susceptible to magnetic fields. Close proximity with a strong magnet can permanently damage the internal compass in your phone.
Warning for allergy sufferers
Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction happens, cease working with magnets and wear gloves.
Serious injuries
Risk of injury: The pulling power is so immense that it can result in blood blisters, crushing, and even bone fractures. Use thick gloves.
Caution required
Handle with care. Rare earth magnets act from a long distance and connect with huge force, often quicker than you can move away.
Operating temperature
Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.
Shattering risk
Despite the nickel coating, the material is delicate and cannot withstand shocks. Do not hit, as the magnet may crumble into hazardous fragments.
Medical implants
For implant holders: Powerful magnets disrupt medical devices. Maintain minimum 30 cm distance or ask another person to handle the magnets.
Keep away from computers
Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, medical aids, mechanical watches).
