Strengths as well as weaknesses of Nd2Fe14B magnets.
Pros
- They retain full power for around 10 years – the loss is just ~1% (based on simulations),
- They show high resistance to demagnetization induced by external field influence,
- A magnet with a shiny silver surface is more attractive,
- Magnetic induction on the top side of the magnet turns out to be extremely intense,
- Thanks to resistance to high temperature, they are able to function (depending on the form) even at temperatures up to 230°C and higher...
- Thanks to versatility in forming and the ability to customize to unusual requirements,
- Versatile presence in future technologies – they are used in magnetic memories, electromotive mechanisms, medical equipment, and complex engineering applications.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Limitations
- To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution secures the magnet and simultaneously improves its durability.
- When exposed to high temperature, neodymium magnets suffer a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
- They oxidize in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
- We recommend a housing - magnetic mount, due to difficulties in realizing threads inside the magnet and complex shapes.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the context of child safety. Additionally, small components of these magnets are able to be problematic in diagnostics medical when they are in the body.
- Due to complex production process, their price is relatively high,
Lifting parameters
Best holding force of the magnet in ideal parameters – what affects it?
- using a plate made of low-carbon steel, acting as a circuit closing element
- with a cross-section minimum 10 mm
- with a surface cleaned and smooth
- without any clearance between the magnet and steel
- during detachment in a direction vertical to the plane
- at ambient temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Gap between surfaces – every millimeter of separation (caused e.g. by veneer or dirt) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops drastically, often to levels of 20-30% of the maximum value.
- Plate thickness – insufficiently thick sheet does not close the flux, causing part of the flux to be wasted into the air.
- Metal type – different alloys reacts the same. High carbon content weaken the attraction effect.
- Plate texture – smooth surfaces ensure maximum contact, which improves field saturation. Uneven metal weaken the grip.
- Thermal environment – temperature increase causes a temporary drop of induction. Check the maximum operating temperature for a given model.
Lifting capacity was determined using a polished steel plate of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the holding force is lower. Moreover, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.
H&S for magnets
Keep away from computers
Do not bring magnets close to a wallet, laptop, or screen. The magnetism can permanently damage these devices and wipe information from cards.
Magnets are brittle
Despite the nickel coating, the material is delicate and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.
Implant safety
Life threat: Neodymium magnets can deactivate pacemakers and defibrillators. Stay away if you have electronic implants.
GPS Danger
GPS units and smartphones are highly susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.
Crushing risk
Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, destroying everything in their path. Be careful!
Do not give to children
Absolutely keep magnets away from children. Risk of swallowing is high, and the consequences of magnets connecting inside the body are very dangerous.
Permanent damage
Avoid heat. Neodymium magnets are susceptible to temperature. If you need operation above 80°C, ask us about HT versions (H, SH, UH).
Do not drill into magnets
Powder produced during machining of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.
Immense force
Handle with care. Rare earth magnets attract from a long distance and snap with massive power, often quicker than you can react.
Sensitization to coating
Nickel alert: The Ni-Cu-Ni coating contains nickel. If an allergic reaction occurs, immediately stop working with magnets and wear gloves.
