Advantages as well as disadvantages of neodymium magnets.
Benefits
- They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They are resistant to demagnetization induced by external magnetic fields,
- The use of an refined finish of noble metals (nickel, gold, silver) causes the element to present itself better,
- Magnets are distinguished by impressive magnetic induction on the outer side,
- 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 freedom in forming and the capacity to modify to client solutions,
- Wide application in electronics industry – they find application in computer drives, drive modules, medical devices, as well as industrial machines.
- Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,
Disadvantages
- Susceptibility to cracking is one of their disadvantages. Upon intense impact they can break. We advise keeping them in a special holder, which not only secures them against impacts but also raises their durability
- Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain durability even at temperatures up to 230°C
- When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
- Due to limitations in realizing threads and complicated shapes in magnets, we recommend using a housing - magnetic mechanism.
- Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which becomes key in the aspect of protecting the youngest. Additionally, small components of these devices can be problematic in diagnostics medical when they are in the body.
- With mass production the cost of neodymium magnets is economically unviable,
Holding force characteristics
Magnetic strength at its maximum – what affects it?
- using a base made of low-carbon steel, serving as a ideal flux conductor
- with a thickness no less than 10 mm
- with an ideally smooth contact surface
- under conditions of ideal adhesion (surface-to-surface)
- for force applied at a right angle (pull-off, not shear)
- at temperature approx. 20 degrees Celsius
Key elements affecting lifting force
- Space between surfaces – 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 – remember that the magnet holds strongest perpendicularly. Under sliding down, the holding force drops significantly, often to levels of 20-30% of the nominal value.
- Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the attraction force (the magnet "punches through" it).
- Material type – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
- Surface structure – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
- Thermal conditions – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost they can be stronger (up to a certain limit).
Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, whereas under shearing force the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate lowers the holding force.
H&S for magnets
Heat sensitivity
Control the heat. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.
Choking Hazard
Product intended for adults. Small elements pose a choking risk, causing severe trauma. Keep away from kids and pets.
Phone sensors
GPS units and smartphones are extremely susceptible to magnetic fields. Direct contact with a powerful NdFeB magnet can ruin the sensors in your phone.
Medical implants
Health Alert: Strong magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.
Hand protection
Pinching hazard: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.
Safe operation
Use magnets with awareness. Their huge power can shock even professionals. Stay alert and do not underestimate their power.
Allergic reactions
Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. For allergy sufferers, refrain from touching magnets with bare hands and choose encased magnets.
Do not drill into magnets
Powder produced during machining of magnets is self-igniting. Do not drill into magnets unless you are an expert.
Eye protection
Beware of splinters. Magnets can fracture upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.
Data carriers
Intense magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Maintain a gap of at least 10 cm.
