Advantages and disadvantages of neodymium magnets.
Pros
- They have unchanged lifting capacity, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
- They are noted for resistance to demagnetization induced by external field influence,
- In other words, due to the aesthetic surface of silver, the element looks attractive,
- The surface of neodymium magnets generates a intense magnetic field – this is a key feature,
- Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
- Due to the ability of flexible forming and customization to specialized requirements, magnetic components can be created in a broad palette of forms and dimensions, which increases their versatility,
- Fundamental importance in advanced technology sectors – they are utilized in computer drives, electromotive mechanisms, precision medical tools, also modern systems.
- Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications
Disadvantages
- To avoid cracks under impact, we recommend using special steel holders. Such a solution secures the magnet and simultaneously increases its durability.
- We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
- Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
- Due to limitations in creating threads and complex shapes in magnets, we recommend using a housing - magnetic holder.
- Health risk related to microscopic parts of magnets pose a threat, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these products can be problematic in diagnostics medical after entering the body.
- With mass production the cost of neodymium magnets is economically unviable,
Lifting parameters
Detachment force of the magnet in optimal conditions – what affects it?
- on a plate made of mild steel, perfectly concentrating the magnetic field
- possessing a massiveness of at least 10 mm to ensure full flux closure
- with an ground touching surface
- without any air gap between the magnet and steel
- under perpendicular force direction (90-degree angle)
- at standard ambient temperature
Practical lifting capacity: influencing factors
- Gap between magnet and steel – every millimeter of separation (caused e.g. by varnish or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
- Pull-off angle – note that the magnet holds strongest 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. Magnetic flux penetrates through instead of generating force.
- Material type – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
- Plate texture – smooth surfaces guarantee perfect abutment, which increases force. Uneven metal weaken the grip.
- Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and in frost gain strength (up to a certain limit).
Lifting capacity was determined by applying a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet and the plate decreases the holding force.
Safety rules for work with NdFeB magnets
Serious injuries
Large magnets can break fingers instantly. Never put your hand betwixt two strong magnets.
Eye protection
Neodymium magnets are ceramic materials, which means they are very brittle. Collision of two magnets will cause them breaking into small pieces.
Allergic reactions
A percentage of the population suffer from a sensitization to Ni, which is the standard coating for NdFeB magnets. Extended handling might lead to a rash. We recommend use safety gloves.
Implant safety
Warning for patients: Strong magnetic fields disrupt electronics. Keep minimum 30 cm distance or request help to handle the magnets.
Powerful field
Exercise caution. Rare earth magnets attract from a distance and connect with huge force, often faster than you can move away.
Flammability
Drilling and cutting of neodymium magnets poses a fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.
Thermal limits
Monitor thermal conditions. Exposing the magnet to high heat will ruin its properties and strength.
Do not give to children
Always keep magnets out of reach of children. Risk of swallowing is significant, and the effects of magnets clamping inside the body are fatal.
GPS and phone interference
A strong magnetic field negatively affects the operation of magnetometers in smartphones and navigation systems. Keep magnets near a device to avoid breaking the sensors.
Electronic hazard
Powerful magnetic fields can corrupt files on credit cards, HDDs, and other magnetic media. Stay away of at least 10 cm.
