Advantages and disadvantages of neodymium magnets.
Pros
- They retain full power for nearly 10 years – the loss is just ~1% (according to analyses),
- Neodymium magnets prove to be exceptionally resistant to magnetic field loss caused by external interference,
- A magnet with a shiny silver surface has better aesthetics,
- Magnets have extremely high magnetic induction on the outer layer,
- 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...
- Possibility of precise modeling as well as adjusting to concrete requirements,
- Universal use in innovative solutions – they find application in mass storage devices, brushless drives, diagnostic systems, also complex engineering applications.
- Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in small systems
Weaknesses
- To avoid cracks under impact, we recommend using special steel holders. Such a solution protects the magnet and simultaneously increases its durability.
- NdFeB magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of strength (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
- When exposed to humidity, magnets usually rust. To use them in conditions outside, it is recommended to use protective magnets, such as those in rubber or plastics, which prevent oxidation and corrosion.
- We recommend a housing - magnetic holder, due to difficulties in creating threads inside the magnet and complicated forms.
- Potential hazard related to microscopic parts of magnets can be dangerous, when accidentally swallowed, which gains importance in the context of child safety. Additionally, small components of these products can be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets can be a barrier,
Pull force analysis
Optimal lifting capacity of a neodymium magnet – what contributes to it?
- with the application of a sheet made of special test steel, guaranteeing full magnetic saturation
- with a cross-section no less than 10 mm
- with a surface perfectly flat
- under conditions of ideal adhesion (surface-to-surface)
- for force acting at a right angle (pull-off, not shear)
- at temperature room level
Practical lifting capacity: influencing factors
- Clearance – existence of foreign body (rust, tape, air) acts as an insulator, which lowers power rapidly (even by 50% at 0.5 mm).
- Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Base massiveness – too thin sheet does not close the flux, causing part of the flux to be wasted to the other side.
- Material composition – not every steel reacts the same. Alloy additives weaken the interaction with the magnet.
- Smoothness – full contact is obtained only on smooth steel. Rough texture reduce the real contact area, weakening the magnet.
- Heat – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity was determined using a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, however under parallel forces the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet’s surface and the plate decreases the lifting capacity.
Safety rules for work with neodymium magnets
Handling rules
Before use, check safety instructions. Uncontrolled attraction can break the magnet or hurt your hand. Be predictive.
Permanent damage
Control the heat. Heating the magnet to high heat will destroy its magnetic structure and strength.
Allergic reactions
Allergy Notice: The nickel-copper-nickel coating consists of nickel. If an allergic reaction happens, cease handling magnets and wear gloves.
Risk of cracking
Neodymium magnets are ceramic materials, meaning they are very brittle. Collision of two magnets leads to them cracking into shards.
Danger to the youngest
Product intended for adults. Small elements pose a choking risk, leading to serious injuries. Store out of reach of kids and pets.
Pacemakers
People with a pacemaker must keep an absolute distance from magnets. The magnetism can stop the operation of the implant.
Keep away from electronics
GPS units and mobile phones are extremely sensitive to magnetism. Direct contact with a powerful NdFeB magnet can permanently damage the sensors in your phone.
Protect data
Avoid bringing magnets near a wallet, computer, or TV. The magnetism can irreversibly ruin these devices and wipe information from cards.
Crushing risk
Risk of injury: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Use thick gloves.
Flammability
Dust produced during cutting of magnets is self-igniting. Avoid drilling into magnets without proper cooling and knowledge.
